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.

# $FreeBSD$
Convert gnu to using SRCTOP Prefer SRCTOP over CURDIR/../../contrib, etc. However, retain the "up one level" instances of ../ because they are really relative to this part of the tree and not a means to find the root of the tree. As such, it's better to leave them since that further the goal of being able to move directories if watned to in the future.

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.
