2286fe7635 Second attempt at eliminating .text relocations in shared libraries
compiled with stack protector.

Use libssp_nonshared library to pull __stack_chk_fail_local symbol into
each library that needs it instead of pulling it from libc. GCC
generates local calls to this function which result in absolute
relocations put into position-independent code segment, making dynamic
loader do extra work every time given shared library is being relocated
and making affected text pages non-shareable.

fe73c506a4 - Reenable Native Language Support in libc. This feature was disabled due
to possible breakages in the catalog handling code.  Since then, that
  code has been replaced by the secure code from NetBSD but NLS in libc
  remained turned off.  Tests have shown that the feature is stable and
  working so we can now turn it on again.

- Add several new catalog files:

  - de_DE.ISO8859-1

25bacc7818 Implement the xdev target. When you define XDEV=arch XDEV_ARCH=arch,
you can build the cross development tools and install them as
$XDEV-freebsd-xxx for each tool.  This allows one to use autoconf to

b61a9dcf3f Implement an idea from Sam Leffler:
make KERNFAST=blah buildkernel
is now a short cut for
	make KERNCONF=blah -DKERNFAST buildkernel

This change works for all kernel config files not named "1".  I did
that to make sure that
	make -DKERNFAST buildkernel
remains the same as
	make -DKERNFAST KERNCONF=GENERIC buildkernel
rather than trying to build and configure "1".  I've never seen a
kernel config file named "1," so I think this is a good compromise.

e68ed79390 Tweak the support for using ldd on 32-bit objects a bit further.
Specifically, build a 32-bit /usr/bin/ldd32 on amd64 which handles 32-bit
objects.  Since it is a 32-bit binary, it can fork a child process which
can dlopen() a 32-bit shared library.  The current 32-bit support in ldd
can't do this because it does the dlopen() from a 64-bit process.  In order
to preserve an intuitive interface for users, the ldd binary automatically
execs /usr/bin/ldd32 for 32-bit objects.  The end result is that ldd on
amd64 now transparently handles 32-bit shared libraries in addition to
32-bit binaries.

042df2e2da Enable GCC stack protection (aka Propolice) for userland:
- 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.

source upgrades by falling back to GNU ar(1) as necessary.  Option
WITH_BSDAR is gone.  Option _WITH_GNUAR to aid in upgrades is *not*

this and to flag the switch to BSD ar(1), should it be needed for

c93073c260 - Explicitly verify if all needed libs were found by ldd(1). Do so
through scanning its output as ldd(1) returns a non-zero status only
  for really abnormal conditions such as an improper file format.
  Now cp(1) won't get bogus "not" and "found" arguments if a lib
  is missing. [1]

- Don't guess if an element of a complex pipeline is assigned to the main
  shell or a sub-shell.  Namely use stdio, not vars, to pass lists out from
  loops.  If using vars, there's the risk that a loop will run in a sub-shell
  and the list won't make it to the main shell.  It appears that braces and
  parens give only limited control over the issue while stdio always works
  as intended.  Apply this solution to both $progs and $libs for consistency,
  although I've failed to go without it only in the $libs part.

519bc416ca Decouple the install tools from the main system as much as possible.
I.e., not only copy them to a scratch dir, but also make them use saved
copies of libraries and locale files.  That gives us several benefits:

1) ABI breakages should no longer affect installworld over the live system.

2) It becomes safe to run installworld while still running the old kernel.
   However, it can be reasonable to save the old /rescue before that to be
   able to run the old reboot(8), as the new binaries are rather likely to
   fail with the old kernel.  Anyhow, it's now possible to upgrade a system
   in a single reboot _reliably_.

3) With a bit of hackery around rtld(8), it becomes possible to do destructive
   cross-installs, e.g., i386->amd64 over the live system.

The only shared item left between the old and new systems is rtld(8),
which cannot be run from a saved copy easily because its full
pathname is stored in the respective field of each ELF executable.
(In theory, that field could be overridden, e.g., from the environment,
but this can lead to security issues.)  That's why a destructive
cross-install isn't possible w/o hackery yet.

152f2a4a96 Always install libpthread.* symlinks if at least one of
the threading libraries is built.  This simplifies the
logic in makefiles that need to check if the pthreads
support is present.  It also fixes a bug where we would
build a threading library that we shouldn't have built:
for example, building with WITHOUT_LIBTHR and the default
value of DEFAULT_THREADING_LIB (libthr) would mistakenly
build the libthr library, but not install it.
