g-ir-scanner fails when using ccache

[Natanael Copa <ncopa alpinelinux org>]

Hi,

I noted that packages like dconf fails to build when CC is set to
"ccache gcc". Setting it to "gcc" makes it compile. I traced it to the
introspection compiler.

I use gobject-introspection-0.9.10

To reproduce, unpack dconf-0.5.1 and run configure. Then make sure
ccache is installed and run make like this:

  make CC="ccache gcc"

I get:
...
  GEN    libdconf.so
  GISCAN dconf-1.0.gir
Traceback (most recent call last):

When CC=gcc then it works.

Thanks!
