Hi,
The fourth part of the patch set rewrites mksignames in such a way
that it works in a cross-compilation environment. It uses gcc -E to
generate the bulk of the signames file, and only does minimal
processing on the build system, in order to avoid accidentally getting
the build system's signal definitions instead of the target system's.
Regards,
Alain
