I had to install some extra packages on my Debian Stretch box to build the documentation:

sudo apt-get install xsltproc docbook-xsl docbook-xsl-ns w3-dtd-mathml docbook-mathml

sudo apt-get install opengl-4-man-doc opencl-1.2-man-doc

contains many man pages, e.g.:

man glDrawArrays

but it does not contain man glRotate. I think this is because the deprecated immediate APIs are not included.

apt-file search glRotate shows a few hits, but they don t seem "official".

Tested on Ubuntu 16.04.
