Yes, and that "fix" is to globally define __pic__ or __PIC__ in the
compiler for all targets when using -fpic or -fPIC.

True, the testcase isn't supposed to work with -fpic/-fPIC, but we
should have a graceful way in the compiler to detect and elide this so
we can run -fpic/-fPIC testsuite passes without getting noise.

It's very important that -fpic/-fPIC be as reliable as possible given
how much GNU systems rely on shared libraries, etc.
