If you need FD-PIC then that's a pretty major toolchain development required. In this case, for x86, that's the most complex of the gcc backends. I think all-told it took us about 3 weeks with 3 of us working on it to get FD-PIC working for the Ubicom32 tools and uClinux port, although I've probably ended up spending another week on the compiler since then to get it to generate good code.
