Subject: tools: fakeroot: rework relocatable patch to avoid LD_LIBRARY_PATH
 usage
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Due to the use of LD_LIBRARY_PATH, the programs running in the fakeroot
environment may end up loading bundled SDK libraries using the system
ld.so.

Rework the relocatability patch to avoid meddling with LD_LIBRARY_PATH
and construct the paths to faked and libfakeroot.so directly.

Fixes: f93cb5c2c8 ("fakeroot: make fakeroot script relocatable")
