Michael Brown e80299c56b [build] Work around -fPIE patched versions of gcc on all architectures 
Several distributions include versions of gcc that are patched to
create position-independent executables by default.  These have caused
multiple problems over the years: see e.g. commits fe61f6d ("[build]
Fix compilation when gcc is patched to default to -fPIE -Wl,-pie"),
5de1346 ("[build] Apply the "-fno-PIE -nopie" workaround only to i386
builds"), 7c395b0 ("[build] Use -no-pie on newer versions of gcc"),
and decee20 ("[build] Disable position-independent code for ARM64 EFI
builds").

The build system currently attempts to work around these mildly broken
patched versions of gcc for the i386 and arm64 architectures.  This
misses the relatively obscure bin-x86_64-pcbios build platform, which
turns out to also require the same workaround.

Attempt to preempt the next such required workaround by moving the
existing i386 version to apply to all platforms and all architectures,
unless -fpie has been requested explicitly by another Makefile (as is
done by arch/x86_64/Makefile.efi).
