xenocara build broken on sparc64 - libdrm fails

Hello,

the xenocara sets in snapshots are more than one month old, so I tried
to build xenocara from cvs. One week ago the build was fine. Now it
errors out at libdrm:

cc -O2 -pipe -g    -I/usr/xenocara/lib/libdrm  -I/usr/X11R6/include -I/usr/include/dev/pci/drm  -DX_PRIVSEP  -DHAVE_VISIBILITY -c /usr/xenocara/lib/libdrm/xf86drmHash.c -o xf86drmHash.o
