[PATCH] removing unused local ccache in patch.diff

[Adrian Buehlmann]

I ran the tests on FreeBSD 6.3:

Skipped test-highlight: missing feature: Pygments source highlighting library
Skipped test-no-symlinks: system supports symbolic links
Failed test-convert-mtn: output changed
Failed test-imerge: output changed
# Ran 254 tests, 2 skipped, 2 failed.

* imerge extension is defunct (see 368a4ec603cc)
* I'm ignoring test-convert-mtn for this
