[tlbuild] asy2.48

[John Bowman]

Hi Norbert,
Yes, you need libglm-dev and need to use CXXFLAGS=-std=c++11 (the default)
not -ansi. I have simplified the signature of createShaderFile
in the attached patch.

You don't want to compile with --disable-gl (except for debugging
compilation issues) but I did add the required conditional to support this
again.
Let me know if there are any further issues.
