Unlinking libiberty fails

[krs013]

Line 41 in msp430-gcc.rb fails to execute because macOS has a fake gcc at /usr/bin/gcc that is actually just Clang. I'm not sure what exactly that piece was needed for or if it's still a problem, but you may want to find a different way to get that value.

Just a thought, as homebrew is a macOS platform, you may be working harder than necessary to use --print-multi-os-directory for that step.

Ah, that’s tricky—thanks for pointing that out. I’m not currently using this recipe, but I’d gladly accept a pull request if you know how to fix this.

Oh, I see. I didn't realize that there was a newer version of mspgcc from ti/somnium. I used to think CCS was enough of a mess already.
