[ccache] Bug compiling package freetype

[Giacomo Comes]

Hi,
I have found a bug in ccache as it fails to compile the package freetype.
I have tested the bug on CentOS 5 and 6 and openSUSE 12.2 with ccache 3.1.9.

This is how to reproduce the bug:
download freetype 2.4.11, untar and run ./configure.
run make
compilation is succesful.

Redo everything but this time in the last step run:
make CC="ccache gcc"

compilation will fail with the error message:

libtool: link: `/dev/shm/freetype-2.4.11/objs/ftsystem.lo' is not a valid libtool object
make: *** [/dev/shm/freetype-2.4.11/objs/libfreetype.la] Error 1

I have no idea if this is due to an already known bug of ccache
or it is something new.  Anyway I'm reporting it.

Regards.

Giacomo
