That was only checked in on a Google branch, so this is not fixed, regardless
of the below.
The check-in applies almost cleanly to GCC 8.2.0, but actually testing it, I
find that it does not work in my test case. I suppose it would work when all
files are put together in a single directory, but that's not the only way
symlinks can be used. I installed packages with DESTDIR into separate
directories, and installed symlinks to the files in each of those using cp -rs.
When the code checks whether spec_machine can be found, it correctly sees that
it can be: GCC is one of the packages that provides that directory. As a
result, -canonical-prefixes is used. However, it cannot find anything from
binutils or glibc there, so things still break.
