When the GNU linker searches for an input file or an archive, if it
finds an incompatible file, it skips it and keeps searching. An object
is incompatible if it is built for a target other than the one being
linked. An archive is incompatible if it contains an incompatible
object. A script is incompatible if it uses an OUTPUT_FORMAT command to
name a target other than the one being linked. The GNU linker issues a
warning when it skips a file, unless --no-warn-search-mismatch is used.
IIRC linkers generally and GNU's in particular
*quietly* skip -L directories they can't find.
Usually that isn't too bad.
Sometimes it's the reason a failure to link is mysterious to me.
It would be nice if, at least in the case of a failure to link,
a failure to find a directory became noisy.
