[PATCH 1/1] config.mak.uname: Darwin: Use clang for Mac OS X 10.6

[tboegi@web.de]

From: Torsten Bögershausen <tboegi@web.de>

Commit
"tree-diff: catch integer overflow in combine_diff_path allocation"
make gcc under Mac OX 10.6 crash like this:

CC combine-diff.o
combine-diff.c: In function ‘diff_tree_combined’:
combine-diff.c:1391: internal compiler error: Segmentation fault

Xcode for Mac OS X 10.6 has both gcc and clang.
Later versions of Mac OSX/Xcode only provide clang, and gcc is a wrapper
to it.
Make Git compile under Mac OS X 10.6 by using clang instead of gcc
