USE_NLS is generally defined for uclibc based system builds
and generally its defined to 'no' there. However this variable
does not exist at all for eglibc/glibc distributions. This
patch adds a weak definition to 'yes' on eglibc based system
builds. This will ease out some of the cryptic contructs we
have to define certain options based on USE_NLS and also
checking got uclibc at the same time to avoid pythong exceptions
when its not defined.
