fpc: disable PIE hardening

Fails with the usual error:

ld: fpmake.o: relocation R_X86_64_32S against `.bss.n_u_$p$fpmake_$$_p' can not be used when making a PIE object; recompile with -fPIE
ld: failed to set dynamic section sizes: bad value

The build system is hard to decipher, so just disable PIE for now.
