glibc-testsuite: Create a recipe to implement glibc test suite

A recipe needs to be created for the test suite due to the dependency
chain between libgcc -> glibc -> libgcc-initial, and the requirements of
the test suite to have libgcc for compilation and execution.

The glibc test suite does not use dejagnu like the gcc test suites do.
Instead a test wrapper script is used along with the assumed dependency
of having the same filesystem available on build host and target. For
qemu linux-user the same filesystem is inherently available, for remote
targets NFS is used. Separate test wrapper scripts are created for qemu
linux-user or ssh targets, with the same TOOLCHAIN_TEST_* variables used for
configuration.
