Remove checkLibraryNameClashes()

Browse Source 
The library name clash checker throws errors when two libraries of the
same name are spotted.  In a previous commit, this function was
rewritten to use fully-qualified names instead, which makes it redundant
to the checker for multiply-declared identifiers.  Since it no longer
serves a clear purpose, the function is being dropped.
