Huge update to the FreeBSD port (i386 part).

Starting with FreeBSD 10, the FreeBSD project has moved from using
gcc/libstdc++ to using a complete C++ stack based on clang/llvm
libc++ and libcxxrt. This new stack has better standards compliance
and has huge similarities with MacOSX but it brought subtle low
level problems for our outdated bridges code.

Don Lewis has done a brave effort to update this code and
has done extensive testing within FreeBSD port. Support
for older versions of gcc has been dropped.
