Throwing in a general -fno-pie does not seem to be the right fix either.
Maybe iPXE should start specifying -fno-pie where needed?
There's logic within arch/i386/Makefile which is supposed to autodetect
compilers that do this and specify the appropriate combination of "do
not use PIE" options. We may need to expand this to handle whatever
Gentoo has done.
What about other gcc options like __FORTIFY__ ?
There's similar logic in Makefile.housekeeping to disable
-fstack-protector if needed.
