This applies the same change as in
760261a3daf98882ccbd177e3133fb4a058f47ad (where they were applied to libcxxabi and libcxx) to libunwind as well.

These options can reasonably be set either as an absolute or relative path, but if set as type PATH, they are rewritten from relative into absolute relative to the build directory, while the relative form is intended to be relative to the install prefix.
