What you effectively seem to be building is a cross-compiler from
x86-glibc-A to x86-glibc-B.  To run your tests, you want a machine
that's running x86-glibc-B.  I would have thought the best way to
achieve this would be to run the tests in a chroot that is your
sysroot.  That's what gcc is compiling for.
