Mark all files used in a standard build of bin-x86_64-efi/snponly.efi
as permitted for UEFI Secure Boot. These files represent the core
functionality of iPXE that is guaranteed to have been included in
every binary that was previously subject to a security review and
signed by Microsoft. It is therefore legitimate to assume that at
least these files have already been reviewed to the required standard
multiple times.

When building the Linux userspace binaries, the external system
headers may have already defined values for the __LITTLE_ENDIAN and
__BIG_ENDIAN constants.
Fix by retaining the existing values if already defined, since the
actual values of these constants do not matter.
