[Mesa-stable] [PATCH] swr: use the correct variable for no undefined symbols

[Emil Velikov]

From: Emil Velikov <emil.velikov at collabora.com>

The variable name was missing a leading LD_, which resulted in the
backend binaries having unresolved symbols.

Thanks to Laurent for the list.

The fix is applicable for stable as well, although the actual pthread
linking may not be. That plus additional [missing] links will be
resolved in that branch.

Laurent, the output of `ldd -r $binary` should be free of undefined
symbols. Can you give it a quick test?

Tim, Bruce - the new backends might need the PTHREAD* bits.
The SCons build has the -Wl,no-undef... parts but one might want to
double-check the binaries it produced.

Thanks
