mesa: fix 32bit cross compilation on a 64bit machine
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.

glsl: fix bug in sampler array indexing
Need to add the 'offset' parameter when indexing the parameter array.
Before, if we were setting arrays of samplers, we were actually only
setting the 0th sampler's value.
Because of how progs/glsl/samplers.c is constructed, this wasn't showing
up as a failure in the samplers_array output.

ARB prog: Set error instead of falling through with incorrect value
If a fragment program only parameter was queried of a vertex program
(e.g., GL_MAX_PROGRAM_TEX_INDIRECTIONS_ARB) no error would be set and
a random value would be returned. This caused 'glxinfo -l' to show
the same values for GL_MAX_PROGRAM_ALU_INSTRUCTIONS_ARB,
GL_MAX_PROGRAM_TEX_INSTRUCTIONS_ARB, GL_MAX_PROGRAM_TEX_INDIRECTIONS_ARB,
GL_MAX_PROGRAM_NATIVE_ALU_INSTRUCTIONS_ARB,
GL_MAX_PROGRAM_NATIVE_TEX_INSTRUCTIONS_ARB,
GL_MAX_PROGRAM_NATIVE_TEX_INDIRECTIONS_ARB as for
GL_MAX_PROGRAM_ENV_PARAMETERS_ARB. This is confusing and incorrect.
