Subject: [PATCH] configure: Silence lld-link when getting the version number
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
In recent lld-link versions, this command prints the version to
stdout, but also prints an error to stderr:
$ lld-link -flavor gnu --version
LLD 4.0.0 (trunk 285641)
lld-link: error: no input files
lld-link: error: target emulation unknown: -m or at least one .o file required
