The fix involved adding a proper build of ld-elf.so.1 ,
and also replacing ldd with objdump (suggested by Garrett Cooper)
to build the list of shared libraries needed by the binaries
and libraries on the target.
improve support for multi-arch and cross-arch builds, by adding
a suffix to the kernel config file and build_directory.
(cross builds not clean yet, a cross-built kernel boots
but fails when starting /sbin/init)
we need to set TARGET and TARGET_ARCH to get a correct WMAKEENV.
I am setting both to i386 since this is what picobsd is used for,
though there might be a better fix.
Add initial support for parallel make. This is disabled right now,
because there are incorrect dependencies somewhere which require
to run picobsd 2-3 times to complete a build.

free from the 2.88MB that we had using El Torito emulation.
The --iso option was already there, just didn't do anything before.

without root privs. This is done, among other things, replacing
the absolute paths in the symlinks with relative paths, so we
do not need to do a chroot to follow them.
Still need to update the manpage.
MFC after: 3 days
have problems with kernels larger than 4MB.
Add a flag to avoid the /boot/loader and use the old method.
Add support for an additional makefile to perform custom manipulation
(this is not documented yet).
Add support for building an ISO image (not complete)
- It is opt-out for now so as to give it maximum testing, but it may be
turned opt-in for stable branches depending on the consensus. You
can turn it off with WITHOUT_SSP.
- WITHOUT_SSP was previously used to disable the build of GNU libssp.
It is harmless to steal the knob as SSP symbols have been provided
by libc for a long time, GNU libssp should not have been much used.
- SSP is disabled in a few corners such as system bootstrap programs
(sys/boot), process bootstrap code (rtld, csu) and SSP symbols themselves.
- It should be safe to use -fstack-protector-all to build world, however
libc will be automatically downgraded to -fstack-protector because it
breaks rtld otherwise.
- This option is unavailable on ia64.
Enable GCC stack protection (aka Propolice) for kernel:
- It is opt-out for now so as to give it maximum testing.
- Do not compile your kernel with -fstack-protector-all, it won't work.

floppy types (in fact, we have only one left!)
Also cleanup some code, using || and && in some places, and
using "export VAR=value" instead of two separate lines.
- use proper make configuration for the build, using
${BINMAKE} as evaluated by ${VERSION}/src/Makefile
- remove -lmytinfo from crunch.conf
- remove support for login_access in tinyware/login
- remove "machine i386" from the kernel config file
It might actually be interesting to extend the script to do
a cross build for !i386 ...

+ declare some shell variables as 'local'
+ add a missing ';;' in a 'case' statement
+ centralize newfs options
+ properly override GID and UID when installing include files and libraries
+ add a missing '-r' in disklabel commands (maybe not necessary, but it
does not harm and it was used in the RELENG_4 version)
+ no more require 'perl' when installing the secondary loader
+ use '-t rsa1' when invoking ssh-keygen
Following a suggestion by Ruslan, the initial creation of the
includes and libraries (and build tools) is now done by
invoking "make buildworld" (with -DPICOBSD which eventually will
limit the amount of stuff built with a 2-line change in Makefile.inc1).
The correct environment is then used for subsequent builds.
Also remove write_mfs_in_kernel.c in favour of using dd
All the above is conditional on __FreeBSD_version, as the previous
method still worked for versions earlier than 500035, and I am
unsure on how the "new" method works for earlier versions.
Finally, note that the crunch.conf files need some work because
some libraries (e.g. gmd) have gone away from the base installation.
filesystem expands the inode to 256 bytes to make space for 64-bit
block pointers. It also adds a file-creation time field, an ability
to use jumbo blocks per inode to allow extent like pointer density,
and space for extended attributes (up to twice the filesystem block
size worth of attributes, e.g., on a 16K filesystem, there is space
for 32K of attributes). UFS2 fully supports and runs existing UFS1
filesystems. New filesystems built using newfs can be built in either
UFS1 or UFS2 format using the -O option. In this commit UFS1 is
the default format, so if you want to build UFS2 format filesystems,
you must specify -O 2. This default will be changed to UFS2 when
UFS2 proves itself to be stable. In this commit the boot code for
reading UFS2 filesystems is not compiled (see /sys/boot/common/ufsread.c)
as there is insufficient space in the boot block. Once the size of the
boot block is increased, this code can be defined.
Things to note: the definition of SBSIZE has changed to SBLOCKSIZE.
The header file <ufs/ufs/dinode.h> must be included before
<ufs/ffs/fs.h> so as to get the definitions of ufs2_daddr_t and
ufs_lbn_t.
Still TODO:
Verify that the first level bootstraps work for all the architectures.
Convert the utility ffsinfo to understand UFS2 and test growfs.
Add support for the extended attribute storage. Update soft updates
to ensure integrity of extended attribute storage. Switch the
current extended attribute interfaces to use the extended attribute
storage. Add the extent like functionality (framework is there,
but is currently never used).

+ fix some dialog entries to correctly modify variables instead of working
in a subshell
+ add a logverbose function for debugging purposes
+ force 512/4096 blocks on filesystems
+ use 'auto' for disklabel so it works irrespective of the floppy size.
This is useful for larger images than 1720k
of the default ones (which could be incorrect when doing cross builds).
Also, try to be backward compatible when compiling wmk (the goal being
able to use the most recent "picobsd" script on a wide range of
source trees).
