"Mac Builder Goma Canary" builder is failing with "Argument list
too long". The length of command line exceeds 220K, so it's
actually long.

Though libtool on Mac does not support @rsp file, it supports
-filelist. So we can pass a file list via a file.
-filelist takes a file list separated by a new line, so we can
abuse rspfile for this purpose.

"solink", "solink_module", and "link" are doing the same thing,
so I believe this is acceptable.
