[ccache] permit ccache to build with clang

[Eitan Adler]

Hi,

I needed the following patch for ccache to build with clang. Without
this I get the following error:

[7905 eitan at radar ~/svn/ccache ]%gmake
 (git)-[master]-
clang -DHAVE_CONFIG_H  -DSYSCONFDIR=/usr/local/etc -I. -I.  -MD -MP
-MF .deps/main.c.d -g -O2 -Wall -W -Werror -c -o main.o main.c
clang: error: argument unused during compilation: '-I .'
clang: error: argument unused during compilation: '-I .'
gmake: *** [main.o] Error 1
