[tlbuild] asy2.49 build

[Norbert Preining]

Hi all,

> I was able to compile it on centos7 (but with --disable-gl) without changes.

after discussion with John he explained that the GLEW call is absolutely
necessary for GL support.

But, in addition, I found out that GLEW is linked against major.minor,
so even binaries built on Debian/stretch (current stable, GLEW 2.0) will
not run on Debian/buster (soon stable, GLEW 2.1):

On build system Debian/stretch (current stable, soon old stable):
$ ldd asy | grep  -i glew
        libGLEW.so.2.0 => /usr/lib/x86_64-linux-gnu/libGLEW.so.2.0 (0x00007fc272faf000)

On Debian buster, soon stable:
$ ldd asy | grep -i glew
        libGLEW.so.2.0 => not found


As a consequence, I will build asy for x86_64-linux and i386-linux
**without** GL support.

Best

Norbert
