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 $CC' with '$CC --version'. This will
effectively verify that $CC (the combination ccache + gcc) is executable
(assuming the compiler has a --version option, which should be the case for
all compilers).
