# For some reason bfd ld doesn't search DT_RPATH when cross-compiling. It's
# not clear why this behavior was decided upon but it has the unfortunate
# consequence that the linker will fail to find transitive dependencies of
# shared objects when cross-compiling. Consequently, we are forced to
# override this behavior, forcing ld to search DT_RPATH even when
# cross-compiling.
