Yes, of course, the la file has nothing to do with the actual linking.
If you want to reduce those warnings, either build with ld --as-needed
or omit the libraries from the command line.

The purpose of this change is the following:
libfoo1 is a normal library, sitting in /usr/lib/libfoo.so|la
libbar1 uses some symbols from libfoo, thus has 'dependency_libs:
/usr/lib/libfoo.la' in it's la-file.
foobar is a program, linking against libbar1, during the linking,
dependency_libs is evaluated, all is fine.
Now libfoo1 is converted to multiarch, going into /usr/lib/<triplet>
foobar is now linked against libbar1, which still points to
/usr/lib/libfoo.la - which doesn't exist anymore, the build fails.

I don't think so. Ideally, all .la files will be dropped from the
archive, once they aren't referenced anymore by other libraries, so it's
an unnecessary helper. New library packages shouldn't install the la
file anyway.
