Looking closely at the logs it uses full path to the compiler. I tried
same and the error is gone. Apparently, smth is broken on my box when
clang is used together with ccache.

  $ /usr/bin/clang -c -fPIC -DPIC -DPIC foo.c

  $ CCACHE_RECACHE=1 ccache /usr/bin/clang -c -fPIC -DPIC -DPIC foo.c
  clang: warning: argument unused during compilation: '-D PIC'
  clang: warning: argument unused during compilation: '-D PIC'

Sorry for the noise.
