From 7e02fd1b7b89245001d3c582c49432c370493d3f Mon Sep 17 00:00:00 2001 From: Eric Botcazou Date: Wed, 21 Sep 2016 12:53:20 +0000 Subject: [PATCH] configure.ac: Do not create links, only substitute the filenames. * configure.ac: Do not create links, only substitute the filenames. * configure: Regenerate. * Makefile.in: Assign the substitution results to variables. (LIBGCC_LINKS): Define. (enable-execute-stack.c): New rule. (unwind.h): Likewise. (md-unwind-support.h): Likewise. (sfp-machine.h): Likewise. (gthr-default.h): Likewise. Add $(LIBGCC_LINKS) to the prerequisites of all object files and unwind.h as prerequisite of install-unwind_h-forbuild.
