RFR: Change newly introduced CLIB variable names to LIBC

[Mikael Vidstedt]

Alan asked why I chose to use “CLIB” for the various variable names/defines I introduced in autoconf/make/code/release file, rather than the much more reasonable “LIBC”. He is, of course, totally right, so this change changes all the occurrences from CLIB to use LIBC instead:

Please have a look and verify the sanity of the changes!

Cheers,
