pkg-infra: better fix libtool files wrt. /usr (branch yem/libtool)

Hello All!

This small series aims at better fixing libtool's .la files.

Currently, we fix .la files by per-prending the path to the sysroot to any path that starts with /usr . However, if either or both of the base directory (basically, $(O) ) or the staging directory are themselves sub-directories of /usr , we avoid doing that transformation, by carefully 'protecting' those two paths, to keep them intact.

However, if the toolchain itself is present as a sub-directory of /usr (i.e. a pre-installed custom toolchain), it may also contain .la files with paths starting with /usr . This means we would currently prepend the path to the staging directory to such paths in those .la files.

Of course, that breaks. :-(

So this series adds two fixes for that:

- first, it properly protects the path to the custom pre-installed toolchain, the same way we handle the base and staging directories, (patch by Arnout),

- second, it moves .la munging into the generic package infrastructure, as even non-autotools-based packages may also install .la files (patch by me).

Changes v1 -> v2:
- add the second patch

Regards,
Yann E. MORIN.
