has not been resolved to a path. That case can occur when the
c++ testsuite is run from the build directory. DejaGNU's
libgloss.exp:get_multilibs runs $compiler without -B, i.e.runs
xgcc without specifying a prefix. Without any prefix, there is
no means to find out where the specs files might be located.
get_multilibs runs xgcc --print-multi-lib, hence we don't actually
need information form a specs file and may skip it here. */
