configure can't find opengl

[Chase Rayfield]

When passing --enable-opengl to ./configure qemu now looks for a glx.pc but this doesn't exist on Gentoo or apparently Fedora 21 according to the mailing list reports.

On my amd64 funtoo box these are the *glx.pc files found
/usr/lib32/pkgconfig/xcb-glx.pc
/usr/lib32/pkgconfig/cairo-glx.pc
/usr/lib64/pkgconfig/xcb-glx.pc
/usr/lib64/pkgconfig/cairo-glx.pc

The list of *gl.pc files on the same box:
/usr/lib32/pkgconfig/cairo-egl.pc
/usr/lib32/pkgconfig/egl.pc
/usr/lib32/pkgconfig/gl.pc
/usr/lib32/pkgconfig/cairo-gl.pc
/usr/portage/media-gfx/nvidia-cg-toolkit/files/nvidia-cg-toolkit-gl.pc.in
/usr/portage/media-libs/opengl-apple/files/gl.pc
/usr/lib64/pkgconfig/cairo-egl.pc
/usr/lib64/pkgconfig/egl.pc
/usr/lib64/pkgconfig/ftgl.pc
/usr/lib64/pkgconfig/gl.pc
/usr/lib64/pkgconfig/cairo-gl.pc

On my sparc64 box:
/usr/lib/pkgconfig/xcb-glx.pc
/usr/lib/pkgconfig/cairo-glx.pc

The qemu ebuild in gentoo has been updated to support --enable/disable-opengl but glx.pc seems to possibly be distro specific?

Confirmed for Debian Jessie, too. The package mesa-common-dev includes /usr/include/GL/glx.h, but only a
/usr/lib/x86_64-linux-gnu/pkgconfig/dri.pc. There is no glx.pc for Debian.
