[Cogl] [PATCH 5/8] build: Move the compiler checks and libtool initialization up

[Robert Bragg]

I haven't looked into this in detail but I was having some libtool
problems trying to build the wip/standalone branch in a clean build
directory because it wasn't creating a ./libtool script. Maybe this
patch needs to be double checked. Currently I can only build the
wip/standalone branch in a build directory that was autogened +
configured on master.

kind regards,
- Robert
