libcompiler_rt.a is a BSD licensed C language runtime, which implements
many routines which are linked into binaries on architectures where
certain functionality is missing (e.g. 64 bits mul/div on i386).
Unfortunately, libcompiler_rt cannot replace libgcc entirely. Certain
features, such as an unwinder for exception handling, are missing.
That's why only libgcc.a is replaced for now, because this one does seem
to be complete.
Tested by: rene (amd64), nwhitehorn (powerpc), droso (i386 exprun)
and many others. Thanks!

and 3.3 (build the modules). IMHO, this makes it a little easier to
track the progress of a kernel build using whereintheworld et al.

change the name of the object tree from ${TARGET} to
${TARGET}.${TARGET_ARCH} so we can do both big and little endian
builds in the same tree.

Rather than having arch specific code in Makefile.inc1, generalize so
that we can control the settings of different options on a per
architecutre basis.

- Rework the wrapper support to check libpkg version as well as pkg_install
version.
- Add libfetch to _prebuild_libs.
- There are no new features introduced.
Notes: the API is not stable, so basically, do not use libpkg in your
projects for now. Also there's no manpage for libpkg yet, because the API
will change drastically. I repeat, do not use libpkg for now.
the buildkernel. This way makeoptions WITH_CTF=yes not only works when
compiling the tradtitional way, but also when using buildkernel. This
does not enable the CTF part of the world, it still defaults to without
CTF info.
The cross/build-tools/bootstrap targets are not affected by this, they
still have and should keep the explicit NO_CTF.

libulog now only provides functions that are used by various packages
from the ports tree, namely the libutempter ones. There is no reason to
link it into the crunch/fixit binaries anymore.
That is, write 'exec 3<&0' instead of '3<&0'. Due to an sh(1) bug fixed in
r199953, the latter also persisted, provided that fd 3 was not open before.
With newer sh or fd 3 open, it would not delete orphaned catpages.

Unfortunately there are two slight problems with that:
- Yacc and lex might generate code that generates warnings because of
this. Require yacc and lex to be rebuilt during bootstrap. I'm not
incrementing __FreeBSD_version here, because I assume someone else
will do this eventually.
- When running `make buildkernel', it uses share/mk from the source
treeo to build aicasm. Because aicasm also depends on lex, this would
break. Lower WARNS to 5 for now. We should just increment it to 6
again somewhere in the very far future.
which disables doing a make obj. Use it when you know it will work
only. KERNFAST now implies NO_KERNELOBJ, since you don't need to keep
doing obj when doing incremental kernel builds.
The information used by the "Last login:"-line is obtained by using
ulog_setutxfile(3) to switch to the lastlog database. Login and logout
are performed using the utility functions ulog_login(3) and
ulog_logout(3).
This also means we must build libulog during bootstrap.

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.
