Alexandre Oliva 898c7238df backport: ltcf-c.sh: Use $objext, not $ac_objext. 
Merged from gcc-3_0-branch:
2001-07-30  Jeff Sturm  <jsturm@one-pont.com>
* ltcf-c.sh: Use $objext, not $ac_objext.
2001-07-27  Mark Kettenis  <kettenis@gnu.org>
* ltcf-cxx.sh: Add support for GNU.
2001-07-22  Timothy Wall  <twall@redhat.com>
* ltcf-c.sh: Don't disable shared libraries for AIX5/IA64.  Preserve
default settings if using GNU tools with that configuration.
* ltcf-cxx.sh: Ditto.
* ltcf-gcj.sh: Ditto.
2001-07-21  Michael Chastain  <chastain@redhat.com>
* ltconfig: Set max_cmd_len to a maximum of 512Kb, as it seems some
HPUX 11.0 systems have trouble with 1MB.  Mark as gcc-local.
* ltmain.sh: Mark as gcc-local.

Usage: $progname [OPTION]... LTMAIN [HOST]
Generate a system-specific libtool script.
--build configure for building on BUILD [BUILD=HOST]
--debug enable verbose shell tracing
--disable-shared do not build shared libraries
--disable-static do not build static libraries
--disable-fast-install do not optimize for fast installation
--enable-dlopen enable dlopen support
--enable-win32-dll enable building dlls on win32 hosts
--help display this help and exit
--no-verify do not verify that HOST is a valid host type
-o, --output=FILE specify the output file [default=$default_ofile]
--quiet same as \`--silent'
--silent do not print informational messages
--srcdir=DIR find \`config.guess' in DIR
--version output version information and exit
--add-tag=TAG append an alternate configuration
--with-gcc assume that the GNU C compiler will be used
--with-gnu-ld assume that the C compiler uses the GNU linker
--prefer-pic try to use only PIC objects
--prefer-non-pic try to use only non-PIC objects
--disable-lock disable file locking
--cache-file=FILE configure cache file
LTMAIN is the \`ltmain.sh' shell script fragment or \`ltmain.c' program
that provides basic libtool functionality.
HOST is the canonical host system name [default=guessed].
