>Description:
libtool can't determine the intended behavior of clang since it's not being 
called via gcc, g++, ld, etc., so it needs to be explicitly specified. This 
problem could possibly arise with other compilers as well, and there should be 
no harm in being explicit.

>How-To-Repeat:
Have clang
Set PKGSRC_COMPILER=clang
Try to build fonts/ttmkfdir2
>Fix:
This diff (applied to patch-aa, not added separately to patches) adds tags to 
hint functionality to libtool without changing the behavior of the build.
