Details

Description:
When using both distcc and ccache, PKGBUILDs that execute gcc in package() fail to build with an error from distcc like:

distcc[52016] (main) CRITICAL! distcc seems to have invoked itself recursively!

Additional info:
* The cause is that CCACHE_PREFIX is set to "distcc distcc" instead of just "distcc", which is because buildenv gets set once for build() and a second time for package() and each time it appends "distcc". So ccache invokes "distcc distcc gcc" and that causes distcc to have a fit.
* I posted a patch at https://lists.archlinux.org/pipermail/pacman-dev/2020-January/023949.html but it wasn't taken in. I ran into this again just now so I decided to file a bug.

Steps to reproduce:
* Enable both ccache and distcc in BUILDENV in /etc/makepkg.conf.
* makepkg any package that invokes the compiler in package(), for example ncurses.
* Observe the error during the "make install" command.
This task depends upon

Can confirm this behavior.
