Rename have-mtls-descriptor to have-test-mtls-descriptor
Since have-mtls-descriptor is only used for glibc testing, rename it to have-test-mtls-descriptor. Also enable tst-gnu2-tls2-amx only if $(have-test-mtls-descriptor) == gnu2. Tested with GCC 14 and Clang 19/18/17 on x86-64. Signed-off-by: H.J. Lu <hjl.tools@gmail.com> Reviewed-by: Sam James <sam@gentoo.org>
