ccache-devel: Update to ccache 3.2

[raimue (Rainer Müller)]

Here is a patch to update ccache-devel to the v3.2 tag of the git mirror.

I am not sure if we want to increase the epoch for this to use the correct 3.2 as version number as I did in my patch or if we want to go with 3.2.0-20141117. I leave that decision to the maintainers.

I also disabled -Werror due to errors like this one:

In file included from conf.c:201:
confitems.gperf:33:16: error: static function 'parse_bool' is used in an inline function with external linkage [-Werror,-Wstatic-in-inline]
 {"stats", 23, parse_bool, __builtin_offsetof(struct conf, stats), ((void*)0)},
               ^
confitems.gperf:54:1: note: use 'static' to give inline function 'confitems_get' internal linkage
__inline
^
static
conf.c:39:1: note: 'parse_bool' declared here
parse_bool(const char *str, void *result, char **errmsg)
^

Since this code will only be compiled during development, only ccache-devel is affected and not ccache.
