TLSDESC is the default on aarch64.  Clang doesn't support
-mtls-dialect=trad.  Its integrated assembler doesn't support the
marker.  LLD's doesn't support R_AARCH64_TLSGD_*/R_AARCH64_TLSLD_*
relocations.  Just skip the tests.

With https://sourceware.org/pipermail/libc-alpha/2021-August/129966.html
("aarch64: Make elf_machine_{load_address, dynamic} robust [BZ #28203]"),
if we allow LLD in configure.ac,
`make check` test results of LLD are on par with GNU ld.
