This was done for the rpi-userland component. It's a sensible thing to
do as many packages require egl or gles libraries.  It's easier to
just add an PKG_CHECK_MODULES to configure.ac then to add a bunch of
different ifdefs for each and every opengl implementation.  Thus, I
believe that this should be included.

TI provides a set of hard float binaries as well; however, they are in a
different download.

Will do.

Sorry about that, they were good comments but I was just trying to get
it functional and most of the comments were cosmetic in nature.  I'll
get them all fixed up soon.
