[ccache] auto-disabling ccache when gcc gets plugins?

[David Givone]

Around line 1601 of ccache.c there are some parameter checks to disable
ccache. The code uses the terminology "too hard" when it disables caching.
You will also need to add a test to test/test_compopt.c and look for the
"too_hard" tests for an example.
