Hello ccache devs,
While running ccache's test suite via `make check` I get output from
'which':

Running test suite base...
-----
This is because CC='gcc -std=gnu99' and test.sh ends up invoking
$(which gcc -std=gnu99). The output seems harmless, and 'which' ends
up finding the right compiler path. I think the following patch could
help:

I hope it's helpful. Thanks,
