[Buildroot] [PATCH] redis: fix build with ccache enabled

[Thomas De Schampheleire]

Some parts of redis fail to build when ccache is enabled, due to one of our
own patches. The construct
    make CC=$(CC) target1 target2
would result in
    make CC=ccache <tuple>-gcc target1 target2

and here <tuple>-gcc would be treated as a target and the compiler used
would be just 'ccache'.

I think this should still be applied for 2013.08.
