* Unbreak build on powerpc and other !x86 archs by moving the
--with-dri-drivers logic from dri/Makefile to the
libGL/Makefile.common file. So the settings are applied to all mesa ports,
this was missed in the 10.6.6 update. [1]
* Don't try to enable OpenCL support on anything other then i386 and amd64. [1]
* Move the texture-float and vdpau logic to Makefile.common even if the latter
isn't supported yet. Keep OPTIONS_DEFINE/DEFAULT in dri/Makefile since they
need to defined before bsd.port.options.mk is included, and they only affect
the dri modules.
* Sed on 11 and 10 supports \< and \> however sed on 9.x and dragonfly do not,
replace the sed keywords with some magic to get the intended results. [2]
