[libc] Allow for externally-defined LITTLE_ENDIAN and BIG_ENDIAN constants

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.
