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.

Back out previous revision until better tested fix is ready.

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.
