# LIBGL_DRIVERS_PATH or LIBGL_DRIVERS_DIR, then in the hardcoded
# location /usr/$(get_libdir)/dri. Ati's libGL does the same
# thing, but the hardcoded location is /usr/X11R6/lib/modules/dri
# on x86 and amd64 32bit, /usr/X11R6/lib64/modules/dri on amd64
# 64bit. So we can either put the .so files in that (unusual,
# compared to "normal" mesa libGL) location or set
# LIBGL_DRIVERS_PATH. We currently do the latter. See also bug
# 101539.
# The problem with this approach is that LIBGL_DRIVERS_PATH
# *overrides* the default hardcoded location, it does not extend
# it. So if ati-drivers is merged but a non-ati libGL is selected
# and its hardcoded path does not match our LIBGL_DRIVERS_PATH
# (because it changed in a newer mesa or because it was compiled
# for a different set of multilib abis than we are) stuff breaks.
# We create one file per ABI to work with "native" multilib, see
# below.
