This test was was failing on GitHub Actions because GA uses Linux and
Linux supports resource usage accounting. Cosmo's compile.com program
imposes CPU, memory and file size limits on both the compiler and the
test programs themselves.
See #1076
Added the `libcxxabi` test suite as found in LLVM 17.0.6.
Some tests that do not apply to the current configuration of
comsopolitan are not added. These include:
- `backtrace_test`, `forced_unwind*`: Use unwind function unsupported in
SjLj mode.
- `noexception*`: Designed to test `libcxxabi` in no exceptions mode.
Some tests are added but not enabled due to bugs specific to GCC or
cosmopolitan. These are clearly indicated in the `BUILD.mk` file.
