Subject: [PATCH] libfprint/build: Ignore LD_LIBRARY_PATH (and use rpath) on
 local binaries

DT_RUNPATH is intentionally searched after $LD_LIBRARY_PATH.
-Wl,--disable-new-dtags switches to the old DT_RPATH tag, which is searched
before $LD_LIBRARY_PATH. So the embedded paths in the build binary will now
win over whatever is in the environment.

Not breaking builds.
