-configure: support builds using ccache
-
-The configure script checks whether CC is executable by means of a check
-'type $CC'. However, when using ccache, CC is normally set to "ccache gcc"
-(using the appropriate paths). Such a compound string is not recognized by
-type, however, and thus configure bails out.
-
-This patch changes the check 'type $CC' with a compile test.

-Note: a simplification of this patch was accepted upstream, but turns out to be
-non-usable by the Xtensa architecture. This was also reported upstream and
-should normally be reverted soon.
