mk/embedded.mk: Don't use -mregparm in core
Unfortunately commit 4eb06d95d882 ("mk: Add -fPIC for x86_64 to
embedded.mk") left -mregparm enabled when compiling objects in core/,
which means that when compiling for i386 those objects are compiled
with a different ABI compared with everything else, leading to hangs
when booting under 32-bit EFI.
We should only enable -mregparm for code that absolutely requires it,
such as dos/crt0.S which would need to be re-written to use another
ABI.
