bad code at -O2. Since this is likely caused by the low-level
optimizer, testing TARGET_ARCH rather than MACHINE_ARCH should
handle ia64 cross-compilation as well. With this work-around
in place, we can release using the current GCC and Binutils
code at the default optimization level on ia64.

Some ports will install with compressed manpages. man handles
this by looking for the .gz version of a man source file.
It is also common to include other files with the .so
directive where commands or functions share a man page.
Traditionally ports have had to handle this by either not
compressing the manpages, or using the _MLINKS macro in the
port makefile to create symlinks to the actual source file,
rather than using .so versions. Notably, the current version
of Xorg port breaks. See ports/113096 and ports/115845.

32 bits, so subsequent compile time assertion:
sizeof inf->stat.st_mtime <= sizeof sec
Would fail because of that. This change is suitable for
general consumption as well, but fix it in our local
patchset as we are near a code freeze.

that the build failure was caused by a computer/sources date/time
mismatch that caused GCC tools to be mistakenly rebuilt again at
an inappropriate time during buildworld, re-linking them against
new libraries instead of host's installed libraries and thus making
them not runnable by the host. Normally they are only built in
the early stage of buildworld (build-tools) that links them against
shared libraries of the host, but if either the system clock or
modification date/time on source files is set incorrectly, make(1)
can be foolished into thinking that tools are stale and will rebuild
them again, now in the "target" environment which is not suitable
for building helper apps that are to be run during buildworld.

Also:
Switch FreeBSD to use libgcc_s.so.1.
Use dl_iterate_phdr to locate shared objects' exception frame
info instead of depending on older register_frame_info machinery.
This allows us to avoid depending on libgcc_s.so.1 in binaries
that do not use exception handling directly. As an additional
benefit it breaks circular libc <=> libgcc_s.so.1 dependency too.
Build newly added libgomp.so.1 library, the runtime support
bits for OpenMP.
Build LGPLed libssp library. Our libc provides our own
BSD-licensed SSP callbacks implementation, so this library
is only built to benefit applications that have hadcoded
knowledge of libssp.so and libssp_nonshared.a. When linked
in from command line, these libraries override libc
implementation.
'target'. Latter is problematic in particular as apparently FreeBSD's
bsd.prog.mk re-defines it under some circumstances. This causes an
unexpected failures like -dumpmachine not working for cc while working
fine for c++.
Do not re-define IN_GCC in multipe places, it gets inherited from
Makefile.in anyway.

first getting the current state with td_thr_getxmmregs_p. Without this,
debugging a threaded app that uses libthr resulted in kernel panics or
spurious SIGFPEs for me.
(As of revision 1.6, sys/i386/i386/ptrace_machdep.c masks off the
reserved bits in the mxcsr register, which prevents the kernel panics.)
Architectures without PT_GETXMMREGS are not affected.

Only PowerPC supports both 32-bit and 64-bit targets and the
BFD_DEFAULT_TARGET_SIZE is used by the binutils code to reflect
the preferred ABI. We define BFD_DEFAULT_TARGET_SIZE for all
platforms, but based on the build machine. As such 64-bit build
machines defined BFD_DEFAULT_TARGET_SIZE incorrectly for 32-bit
targets, but since this only affects PowerPC it went unnoticed
for a long time.
The fix is to define BFD_DEFAULT_TARGET_SIZE based on the target
architecture.

NetBSD version is a feature-to-feature re-implementation of GNU
gzip using the freely-redistributable zlib and this version is
expected to be mostly bug-to-bug compatible with the GNU
implementation.
- Because this is a piece of mature code and we want to make
changes so it is added directly rather than importing to
src/contrib.
- Connect newly added code to src/usr.bin/ and rescue/rescue
build.
- Disconnect the GNU gzip code from build for now, they will
be eventually removed completely.
- Provide two new src.conf(5) knobs, WITHOUT_BZIP2_SUPPORT and
WITHOUT_BZIP2.
