fpc: add support for i386

[barracuda156]

Just to track the issue for now. I have rewritten extract phase (dmg is different, PowerPC implementation does not work), but build fails quickly. It also asks for clang as assembler, which should not be forced on older systems.

This merely introduces basic support for i386, it will not build, as of now:

Using -Aas-darwin picks the right assembler, but then it fails on:

cfi directives are indeed not supported, AFAIK.

[kencu (Ken)]

you need to use clang as the assembler on older systems to get cfi directive support.
