[PATCH] D32109: [Driver] Limit .exe extension addition to Windows hosts

[Shoaib Meenai via Phabricator via cfe-commits]

smeenai created this revision.

The driver should invoke lld as `lld-link` rather than `lld-link.exe`
when cross compiling.

The alternative would be to teach lld's build system to always produce
`lld-link.exe` even on non-Windows hosts, but I think it's cleaner to
change the driver to respect the host system's executable suffix (or
lack thereof).
