AIX uses ".a" for both static and shared library extensions.

When cross compiling on a 64bit machine, gen_matypes.c is build
for the host machine (64bit) but must generates code for the target
machine (32bit). This causes wrong offsets all over the place and
crashes googleearth on my machine. Solution is to add -m32 when
cross compiling.

Attached patch is compatible with linux-x86-32 and autoconf based
builds.

This adds two --with configure options for setting defines for
MAX_WIDTH and MAX_HEIGHT.  It's conceivably just as easy to define
these in CFLAGS manually, but this way users don't need to know
about internal Mesa details.

Patch updated by BrianP to set DEFINES, not CFLAGS.

The special feature of bin/minstall to copy symlinks is only ever needed
when installing libraries which may have .so symlinks. All the headers
and directories can use a normal install program.

These two modes are separated as $(INSTALL) and $(MINSTALL) to allow the
user (or autoconf) to override installing normal files as they please.
An autoconf check for the install program has been added and will be
used in preference to minstall when available.

Here is a couple of fixes for GNU/Hurd:
- dri_interface.h: no libdrm support either.
- configure.ac:
 - GNU/Hurd is a GNU OS with _GNU_SOURCE and PTHREADS.
 - GNU needs a couple of flags like other OSes

This rewrites the sparc GLAPI code so that it's PIC friendly and works
with all of the TLS/PTHREADS/64-bit/32-bit combinations properly.

As a result we can turn SPARC asm back on.  Currently it's only
enabled on Linux, as that's the only place where I can test this
stuff out.

For the moment the cliptest SPARC asm routines are disabled as they
are non-working.  The problem is that they use register %g7 as a
temporary which is where the threading libraries store the thread
pointer on SPARC.  I will fix that code up in a future change as it's
a pretty important routine to optimize.

Like x86 we do the runtime patch as a pthread once-invoked initializer
in init_glapi_relocs().

Unlike x86, however, our GLAPI stubs on SPARC are just two instruction
sequences that branch to a trampoline and put the GLAPI offset into a
register.  The trampoline is what we run-time patch.  The stubs thus
all look like:

glFoo:
	ba		__glapi_sparc_foo_stub
	 sethi		GLAPI_OFFSET(glFOO) * PTR_SIZE, %g3

This actually makes generate_entrypoint() a lot simpler on SPARC.  For
this case in generate_entrypoint() we generate stubs using a 'call'
instead of the 'ba' above to make sure it can reach.

In order to get a proper tail call going here, in the unpatched case,
we do several tricks.  To get the current PC, for example, we save the
return address register into a temporary, do a call, save the return
address register written by the call to another temporary, then
restore the original return address register value.  This is to
avoid having to allocate a stack frame.

This is necessary for PIC address formation.

This new GLAPI scheme lets us get rid of the ugly SPARC GLAPI hacks in
__glXInitialize() and one_time_init().

You don't need libdrm_radeon for the legacy driver to build,
only for the experimental mm/cs paths.

	It is only the i965simple pipe driver that was broken
	in the gallium-texture-transfere merge that is being
	disabled, mothing more nothing less.

	FYI, there never where working i965 hardware support
	in gallium anyways.

Maybe this should turn into an option (--disable-glew), but for now just
enable glew all the time.

This is not the proper approach to disabling assembly. If there are bugs,
they should be fixed or the assembly can default to off.

This makes the GLU .pc file a little simpler, too.

The pkg-config files have been filled in more thoroughly to allow users
to use mesa more effectively. By adding metadata to Requires.private,
Libs.private and Cflags, we can ensure that all the libraries and
headers will be found in all situations. However, the full substitutions
are only done when using the configure script.

This also fixes the glu pkg-config file to account for using GL or
OSMesa.
