Big endian counterparts are not needed since
we already add the proper endianness to final
config as seen in uclibc-config.inc
The difference between arm and armv5te configs
were also superficial since all it did was select
arm926t which made sure that right mtune and march
flags were passed to gcc when building uclibc
We already do that via passing them in
UCLIBC_EXTRA_CFLAGS.
Similarly for other architectures the features
are really taken care of in config mangler and
machine config fragments are no longer needed
