From 06ebdaa5c8f9721acf93cc3e75a877a3c963867f Mon Sep 17 00:00:00 2001

Subject: [PATCH] giscanner: add a --lib-dirs-envvar option
By default LD_LIBRARY_PATH is set to the list of target library paths;
this breaks down in cross-compilation environment, as we need to run a
native emulation wrapper rather than the target binary itself. This patch
allows exporting those paths to a different environment variable
which can be picked up and used by the wrapper.
Upstream-Status: Pending
