Subject: 	* configure.host: Incorporate host Makefile fragments by setting
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f515fb2f93d81fb401d86f9db2bf3c96cd659737;p=binutils-gdb.git

	* configure.host: Incorporate host Makefile fragments by setting
	shell variables.
	* configure.in: Call AC_PROG_CC.  Substitute CFLAGS, HDEFINES and
	AR.  Call AC_PROG_INSTALL.  Substitute CC_FOR_BUILD, choosing a
	value based on whether the code is being compiled by a cross
	compiler.  Don't substitute host_makefile_frag or frags.
	* aclocal.m4: New file to define local AC_PROG_CC.
	* configure: Rebuild.
	* Makefile.in (INSTALL): Set to @INSTALL@.
	(INSTALL_PROGRAM): Set to @INSTALL_PROGRAM@.
	(INSTALL_DATA): Set to @INSTALL_DATA@.
	(AR): Set to @AR@.
	(CC): Define as @CC@.
	(CFLAGS): Set to @CFLAGS@.
	(CC_FOR_BUILD): Set to @CC_FOR_BUILD@.
	(@host_makefile_frag@): Remove.
	(ALL_CFLAGS): Change $(HDEFINES) to @HDEFINES@.  Move $(CFLAGS)
	after other options.
	(config.status): Remove dependency upon @frags@.
	* config/*.mh, config/README: Remove.
