I see. Not sure if the same problem is there. I do find the gcc search
path reordered mysteriesly without any sane guess for the reason.

The safer way to do is cp (or hardlink) everything over. If it is
copied, pay attention to the disk space. Finally remove the old Prefix.

cp -a $BPREFIX $EPREFIX
...
...
...
...
rm -rf $BPREFIX
