In this case, ccache apparently does not realize that the world stage is
using the toolchain built during the cross-tools stage, which usually is
in /usr/obj/usr/src/tmp/usr/bin.

This toolchain uses another include and lib path, e.g. it only refers to
headers and libraries under /usr/obj, specifically *not* those in the
base system.

In Volodymyr's original log, you can see /usr/bin/ld being invoked by
the compiler driver, not /usr/obj/usr/src/tmp/usr/bin/ld.  I think
ccache invokes /usr/bin/cc, instead of /usr/obj/usr/src/tmp/usr/bin/cc.

Normally ccache searches the PATH to find the 'real' cc executable, but
I am not sure why this goes wrong during the world stage.  It would be
interesting to see some verbose logging from ccache, to see how it finds
the cc executable here.
