Currently my time is limited, but I made an
intermediate commit
   http://svn.blastwave.org/trac/changeset/2075
for merge-support. Proper handling of isaexec is
still missing. The implementation follows what I
have outlined above. Installations still go to
DESTDIR, but the package is build from DESTBUILD.
The files are copied from DESTDIR to DESTBUILD during
the merge phase. There are default-scripts for
verbatim-copying and relocation to ISA subdirs
which are preselected depending on the number of
ISA build. The scripts can be easily replaced
by custom scripts. Relocation during copy is done
with regular expressions as parameters to 'pax'.

After isaexec is handled properly I'll write up
some documentation and try to get this to trunk/.


Feedback is very welcome!

Best regards
