With the patch series from Thomas De Schampheleire that I have just
committed, I think this patch is no longer necessary: all dependencies
that are pulled by the support/dependencies/dependencies.mk code are no
longer built through ccache, they are all built with HOSTCC_NOCCACHE.

Note that the patches from Thomas have been committed in the 'next'
branch, they will be part in the 2013.11 release of Buildroot. They
will land in the 'master' branch of Buildroot when 2013.08 is released.

Best regards,

Thomas
