This patch is a quick proof of concept to show how source code could
be shared between recipes which use ${B} to have a separate build
directory compared to source directory ${S}.
Issues:
a) gcc uses sed and creates config files against ${S} which means
the directory should not be shared. Need to change the way that works.
b) Could be extended to cover eglibc except there is a patch applied
against nativesdk versions which again makes the source incompatible.
c) Need to clean up the layout in work-shared and make a directory level deeper
to ensure patch separation.
d) clean task does not remove stamps
