That looks like a bug in either cwrappers or a latent bug in ccache
code that triggered by cwrappers.  I would set PKG_DEBUG_LEVEL=1 (or
maybe 2) and capture the output, and try to find where the links are
created and trace it down.

I suspect most peopel are building with their native compiler and don't
notice, because at first glance this bug seems to be only when system
gcc and chosen gcc differ.
