You've build and installed libdrm before? If it's installed in a non
standard path you have to tell pkg-config where it has to search for it
(PKG_CONFIG_PATH).

I'm unsure about that. Do you've installed the development packages for
util-macros and xorg-server?
Do those files exist:
    /usr/share/aclocal/xorg-macros.m4
    /usr/share/aclocal/xorg-server.m4

The macro XORG_DRIVER_CHECK_EXT is defined in the latter one.

configure should have checked for libXrandr and it should have failed if
it's not available. What's the output of:
    pkg-config --libs xrandr
