Yes, I'm trying for now to just make changes that remove the small bits of
friction for cross-compiling and then testing using qemu-user as a litmus test
rather than (for now) make it "officially supported".
It is indeed correct that there's no problem with the regular tests in
clang/test (other than clang/test/Driver/env.c if you need QEMU_LD_PREFIX
passed through, as the test strips envvars - but of course for the
lit-orchestrated tests we already have a mechanism to skip tests downstream by
configuring the LIT_ARGS).
