Tests in the `cross-project-tests/debuginfo-tests/llgdb-tests` directory run gdb on non-darwin platforms. gdb versions less than 10.1 cannot parse the DWARF v5 emitted by clang, and DWARF v5 is now the default, so these tests fail on Linux with gdb versions less than 10.1. This patch lets us XFAIL the tests under these conditions. Add `gdb-clang-incompatibility` to the `available_features` in `cross-project-tests/lit.cfg.py` when clang's default DWARF version is 5 or greater and the gdb (if found) version is less than 10.1.
