Some installations have several python versions installed. Allow user
to choose which one to use by setting $PYTHON.

Automatically discover command line options to make clang and
gcc behave in same way.

Tested with qemu.

This allows providing separate LDFLAGS for build and host environments, which
are not necessary the same for cross-compile case. In particular, it allows
building host programs statically to not depend on presence of libraries at
run-time (e.g. MinGW DLLs on Windows) while continue to use default dynamic
linking at build time.

Also fix obsolete comments in confgure.ac - we do use different environment
for build and host now.

* docs/grub.texi (Getting the source code): Likewise.

	involved or only thumb2 is used.

	* INSTALL: Note that GRUBwas successfully compiled with clang 3.2 for
	ppc.

Generate Makefile.*.am directly from gentpl.py, eliminating the use of Autogen.  The Autogen definitions files remain intact as they offer a useful abstraction.

	* INSTALL: Mention ARM compilation with clang.

	* configure.ac: compute TARGET_RANLIB.
	* INSTALL: Document TARGET_RANLIB

	Based on patches from AROS.

	* acinclude.m4: Determine whether nm support -P and --defined-only.
	* configure.ac: Add TARGET_ to all variables pertaining to target
	that don't have it yet.
	* gentpl.py: Likewise.
	* grub-core/Makefile.am: Likewise.
	* grub-core/genmod.sh.in: Likewise.
	* grub-core/gensyminfo.sh.in: Handle OpenBSD and other non-GNU nm
	as well.

	and decreasing prerequisites.

(libdevmapper, ncurses, libusb, SDL, FreeType, GNU Unifont).

	* INSTALL: Add gettext as a dependency and add qemu to a new section
	"Prerequisites for make-check".

	autoconf >= 2.60 support $(localedir).

	* INSTALL: Note that autoconf 2.60 is required.
	* configure.ac (AC_PREREQ): Bump to 2.60.
	* util/grub.d/10_kfreebsd.in (TEXTDOMAINDIR): Set to lowercased @localedir@.
