Romain Naour 41eb72120a package/mesa3d: allow to enable OpenGL texture float support
While testing on a PC target with an HD6310 graphic card, the
OpenGL support was in "compat profile" mode (i.e OpenGL 2.1).

Extended renderer info (GLX_MESA_query_renderer):
    Vendor: X.Org (0x1002)
    Device: AMD PALM (DRM 2.49.0 / 4.10.4) (0x9802)
    Version: 17.0.2
    Accelerated: yes
    Video memory: 256MB
    Unified memory: no
    Preferred profile: compat (0x2)
    Max core profile version: 0.0
    Max compat profile version: 2.1
    Max GLES1 profile version: 1.1
    Max GLES[23] profile version: 2.0
OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD PALM (DRM 2.49.0 / 4.10.4)
OpenGL version string: 2.1 Mesa 17.0.2
OpenGL shading language version string: 1.30

OpenGL ES profile version string: OpenGL ES 2.0 Mesa 17.0.2
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 1.0.16

It turn out that texture float support was missing...

Add a new option to let the user disable this feature if
it doesn't comply to the SGI license.

help
GL_ARB_texture_float is required to enable GLX core profile
(OpenGL3.x) otherwise the compat profile is used
(OpenGL2.1).
The source code to implement ARB_texture_float extension is
included and can be toggled on at compile time, for those
who purchased a license from SGI, or are in a country where
the patent does not apply, etc.
Please consult docs/patents.txt with your lawyer before
building Mesa.
Also, note that this option doesn't affect all drivers. Some
drivers have support for texture float enabled
unconditionally.
If unsure, say N.
