directory for programs used by the driver is actually the standard
behavior we want to be compatible with GCC cross compilers -- it isn't
specific to SUSE or any other distro.
Also start fleshing out testing of the different cross compilation
patterns, both with a new very bare-bones tree of cross compilers and by
extending the multilib trees. Currently, we don't correctly model doing
a cross compile using the non-triple target of a bi-arch GCC install,
but I'll add support for that (and tests) next.

configuration, although the test still stubs out more directories than
are necessary or common in order to exercise all of the lookup paths
observed with upstream GCC.
This finishes testing the distribution-independent and
GCC-installation-independent parts of the library path search logic.
More testing is still needed for the triple detection, GCC-installation
detection, and handling distributions with unusual configurations.
