There's a bunch of these failing, and it's a little weird.
They're failing because they're assuming that `ar` and `objcopy` (and maybe
other bits of binutils` live in the llvm `bin/` directory, rather than
`/usr/lib` (or `/usr/local/lib`, or anywhere else in $PATH).
I'm not sure if this is intended, but, that said, I don't think it's great. We
might:
a) Add options to `dotest.py` to override the binaries, or, more generally the
binutils directory in which the tests should look
b) Fallback to $PATH in case there's no `ar` or `objcopy`.
c) Create symlinks from `llvm-ar` and `llvm-objcopy` to `ar` and `objcopy` in
the `bin` directory (I really don't like this one)
d) If the compiler used is clang (dotest already has logic for that, prepend
the `llvm-` prefix to the executables)
e) you name it</pre>
