[Buildroot] CCACHE_DIR

[Fredrik Roubert <roubert@df.lth.se>]

Hi!

Currently buildroot hardcodes the ccache directory patch, with the
consequence that the built toolchain can't be used outside of the
buildroot build tree.

Three months ago, Ed Swierk suggested on this mailing list to change
that behaviour:

http://www.busybox.net/lists/buildroot/2006-July/000027.html

As far as I can see in the archives, there was no response to his mail.
From my point of view, his suggestion is a good one and it would be a
good idea to apply his patch to buildroot. I therefore attach his patch
to this mail (so that everyone can see it immediately, it's very short),
and ask for anyone who thinks that this patch is a bad idea to explain
why.

Cheers // Fredrik Roubert
