On Windows hosts, the error message will be something like
`c:\src\llvm-project\out\gn\bin\llvm-ranlib.exe: error: Invalid option: '--D'`.
Due to the .exe after llvm-ranlib the existing CHECK lines do not match.
Fix this by ignoring the program name and starting the check line at "error:".
It appears that Windows hosts always report rwxrwxrwx even with the
chmod 644 invocation. As this test only cares about the timestamps
and not the permissions, use a regex wildcard instead.
I have been trying to build CheriBSD (a fork for FreeBSD for the CHERI
CPU) with LLVM binutils instead of the default elftoolchain utilities.
I noticed that building static archives was failing because ranlib is
invoked with the -D flag. This failed with llvm-ranlib since it parses
the -D flag as the archive path and reports an error that more than one
archive has been passed.
