The differences are very subtle:
make drivers/staging
always succeeds, does nothing at all because the directory exists
make drivers/staging/
descends into that directory to build all the files in it, but does
not try to link the modules
make M=drivers/staging
From the output you get, I think this must try to link the modules
against the previously-build vmlinux file, which for some reason
fails here. I suggested doing 'make' to rebuild everything including
vmlinux, so it is up-to-date with your current configuration.
