# $NetBSD: libtool-fix-la,v 1.22 2003/09/02 06:59:51 jlam Exp $
#
# 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.
