there are certain parts of build process which could be shared e.g.
native sysroot
and nativesdk package builds across target system library selections.
and we build
a lot of native packages it will be good if they could be shared
secondly the all-*-* package builds could be shared as well. Similarly
multimachine build is another aspect which could share builds too
having selected same C library.

Many users of oe would be development tool vendors who have BSPs for
many processor boards and C libraries and they would like to have this
possibility
