Remove empty generated file upon gperf failure

Prior to this change the build could fail as follows, if gperf is not
available (or fails):

- make(1) stops due to the gperf error, but an empty target file
(cfns.h) is still created
- the empty cfns.h is newer than the source cfns.gperf so it is not
regenerated on subsequent builds
- the gcc build fails (undefined reference to libc_name_p)

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.

NOSHARED -> NO_SHARED

Start the dreaded NOFOO -> NO_FOO conversion.

OK'ed by: core

For variables that are only checked with defined(), don't provide
any fake value.

Bmake glue for GCC 3.4.2-prerelease.

Fixed style of DPADD and LDADD assignments as per style.Makefile(5).

Update bmake bits to build GCC 3.3.1-prerelease.

Gperf is usable again.

Don't depend on gperf.

Restore some of the implementation from the Bmake gcc 2.95 bits.
In the end, I can do things more like the previous Bmake bits than was
apparent in the middle of the gcc31 WIP.

I was finally able to repeat the -j breakage on one of my machines. Fix it.
I borrowed some ideas from Ruslan, and made the style match cc_tools/Makefile

Tidy up the cleanfiles.

Make the YACC'ing more bullet proof.

Change YACCing.

Fine! I cannot freaking take the bikeshed any more.
These binaries will be static, peroid.

Bmake bits for GCC 3.1.

MFC: tidy up YACCing.

Set NOSHARED conditionally.
