| | | | | | | | | | | | | | | | | | | | | Currently gallium's xlib target will fail to link due to multiple definitions of all the symbols in libmesautil, this only shows up in autotools, and not in meson due to differences in the way that meson and autotools handle linking static archives into static archives. Autotools uses -Wl,--whole-archive implicitly, meson requires this behavior to be opted-into. The solution is just to remove libmesautils from the libgl-xlib target, since it will get all of those symbols form libmesagallium. I've dropped the link from meson as well, it doesn't seem to hurt anything and should make linking just a little faster.
