Does this help?
fpc.i386: E: statically-linked-binary /usr/lib/fpc/2.2.2/ppc386
fpc.i386: E: missing-PT_GNU_STACK-section /usr/lib/fpc/2.2.2/ppc386

That's a message I get when checking the fpc-2.2.2 rpm's from Fedora. This
message is generated on all executable in the rpm.

I'll add the linker-option to the fpc.cfg in the Fedora(10) rpm's.
