autotools: Fix interaction with bitbake -b

If you run bitbake -b on something using autotools with dependencies on

m4 files, it currently fails as the TASKDEPDATA is incomplete for
bitbake -b
and this means the relevant macros aren't found.

Work around this by adding *all* m4 files for the -b case (and show a warning).
