The problem with doing a uClibc patch is that it will only work with internal uClibc toolchains: all uClibc toolchains will continue to be broken. So we might want to do both: 1/ Fix uClibc properly, so that in the future (3-6 months from now), we can get rid of the mesa3d specific fix, after most of the external uClibc toolchains have been updated. 2/ Keep a mesa3d workaround for a little while.
