I didn't see any explicit glibc suffixes in the switch case for other arches hence
the above.

Actually autoconf automatically defines LIBC_{GLIBC,UCLIBC} based on the triplet -
so u get the desired multiplexer for driver configuration already - although I
doubt differences will be needed for ARC for uclibc/glibc !

In light of above, Cupertino pointed me another thing which we need fixing -
something like below
