ccache... it causes big problems when CC='ccache real-gcc' is set and
ccache-native gets rebuilt in parallel.  A customer had problems when
building apr-utils (libtool reported missing '--tag=cc' option) which
are very likely related to a no-ccache -> ccache-available situation.

It is very difficult to recover from such things because CCACHE is in
BB_HASHBASE_WHITELIST.
