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. Signed-off-by: Matt Fleming <matt.fleming@intel.com>
