switch clang version for editors/libreoffice

[Brooks Davis]

The following patch switches the clang version used by
editors/libreoffice from devel/clang (clang 3.2) to devel/clang32 (also
clang 3.2, but installed with "32" suffixed on binaries so as not to
conflict with other reversions).  I've tested the patch on 8.4 amd64
using redports and clang32 is properly detected and builds.  There are
some leftovers reported but I believe they are not my fault.

https://redports.org/~brooks/20131028171312-09199-155471/libreoffice-4.0.6.log

Please approve or commit this patch.  I'd like to remove the current
lang/clang soon.

Thanks,
Brooks
