Unbreak amd64<->i386 cross builds.

The driver-XXX.c files used for host CPU detection with -march=native
should not be compiled in the cross-tools case (where -march=native makes
no sense). This fixes cross-building x86 toolchains on non-x86 systems.

Update bmake glue to build GCC 4.2.

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.

Minor Makefile cleanup. Do not use Makefile variables named 'version' and
'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.

Bmake glue for GCC 3.4.2-prerelease.

Bmake bits for Gcc 3.1.

Partially made possible by: Wilko.Bulte@compaq.com

Break some things used by the front-ends from Makefile.inc that cannot
be used build-wide for GCC 3.1.
