[Buildroot] [PATCH] package/gcc: fix list of files of patch file to hash for ccache

[Yann E. MORIN]

When we build the list of patches to include to compute the hash for
ccache, a typo precented the special gcc-initial/ and gcc-final/
directories from a global patch dir to be included in the caclculation.

Fix that by properly expanding the $(PKG) variable.
