rstrip.sh breaks private rpaths via PATCHELF --set-rpath

Environment: all

Description:
Samba4 by default uses two rpaths, one public (/usr/lib) and a private (/usr/lib/samba), so all bins have those set to: /usr/lib/samba:/usr/lib
The default RSTRIP macro will break those paths via rstrip.sh to:
/usr/lib/samba XXXXXXXX

This results in broken bin's and my temp fix is this:
RSTRIP:=:

Just wanted to ask if this is a bug we want to fix, by allowing multiple rpaths in bins, if they are defined or keep as samba4 specific build quirk?

PS: The main use-case is to avoid/circumvent build issues and let samba use some of its own bundled system lib versions, like tevent or tdb, com_err and than make those private to avoid breaking other packages.

The rstrip.sh script is supposed to retain paths starting with /lib or /usr/lib so I'm not sure whats wrong there. Maybe try adding some debug echos to rstrip.sh

RSTRIP:=: is used in multiple places. I assume for similar reasons.

In any case, if this is really a bug, it belongs at https://bugs.openwrt.org
