handle builds whenever libdrm is not installed

As mentioned in bug 73777 I've folded all three possible fixes in a single patch, to minimise disruption, but if you prefer I can split them apart.

Patch identical to the one in bug 73777 attached.

The latest git version of mesa fails to build:

Same error here on current git.

Interesting... where you guys when I've asked people to test the patches :)

Jos van Wolput, Fabio Pedretti
Rather than throwing random fragments of the build log, I would appreciate if you guys give us at least the configure options that you're using.
Did you guys checked the attached patch ? Might be worth attaching the build log before/after applying it.

I've sent a patch for this not 5 minutes ago.

Just pushed a couple of fixes that should address all the reported issues.

Namely - bug 73776, bug 73777 and the pipe-loader issue reported via irc and here.

Vinson, please update the bugs when you have the chance to check the fix.

    loader: ifdef libdrm specific code and include
    
    Mesa provides the flexibility of building without the
    need to have libdrm present on the system. The situation
    has regressed with the recent commit
    
    commit 8c2e7fd8460750543367053b1be9368cc38e1d6a
    Author: Emil Velikov <emil.l.velikov@gmail.com>
    Date:   Fri Jan 10 23:36:16 2014 +0000
    
        loader: introduce the loader util lib
    
    By isolating libdrm code by #ifndef __NOT_HAVE_DRM_H we
    can have libdrm-less builds on across all build systems.
    
    This patch converts Android's _EGL_NO_DRM to __NOT_HAVE_DRM_H
    to provide consistency with the other cases within mesa, allows
    compilation of libloader on libdrm-less scons and conditionally
    links against libdrm if present under automake.
