llvm way only tests?

[Gabor Greif]

Hi all,

what is the magic incantation for running tests only when the llvm
tools (e.g. `opt`) are around?

I am currently declaring the test as

test('T15155l',
  [ only_ways(llvm_ways),
  ], run_command, ['$MAKE -s --no-print-directory T15155l'])

but it won't be included neither in the optasm builds (which is okay)
nor in the llvm builds (gets skipped unexpetedly) I looked at the
other test which are declared similarly, and they behave just like
mine.

What I am doing wrong?

Thanks,

    Gabor
