Strip ccache from $Config{cc}

When building with -Dcc="ccache cc", $Config{cc} would also end up with
this setting. If that perl is then distributed, no XS will be able to
build if the target machine has no ccache installed/available

With this change, the whole build of perl itself will use ccache, but
$Config{cc} will have it stripped, so all modules (lib/cpan/ext) will
not use ccache. A correct installation of ccache however does not need
$CC to include the ccache prefix, so it is essentially a setup problem
on the building host.
