# For *.la files, in the "relink_command" line, we make the following
# replacements:
#
# "libfoo.la" -> "-L./.libs libfoo.la"
# "dirpath/libfoo.la" -> "-Ldirpath/.libs libfoo.la"
#
# This allows the libraries to be found within ${WRKSRC} during
# relinking. We rely on the proper rpath settings to be set by libtool.
#
# For the *.lai files, in the "dependency_libs" line, we remove
# redundant -Ldir and -llib options. We also make sure that we don't
# ever reference other .la files, only referring to other libraries
# via the usual "-L/path -llib".
