This looks like it could have problems with installed toolchain testing.
With installed testing there is no build directory, but you don't need to
pass any special -B, -L etc. options or set LD_LIBRARY_PATH; instead the
user creates site.exp (with most of the variables gcc/Makefile.in puts
there, but not "rootme" or "TESTING_IN_BUILD_TREE") and arranges for the
compilers to be in the PATH and any necessary directories to be in
LD_LIBRARY_PATH, then runs "runtest --srcdir=whatever/testsuite
--tool=libgcc-math". This should then run the compilers in the manner a
normal toolchain user would, rather than with lots of special options to
find things in the build tree.
Disabling most of the special handling if the appropriate directories
aren't found should suffice. The libstdc++ testsuite definitely works for
installed testing.

For example, don't do this if blddir wasn't found.
