Soften the wildcard to .data.$L* to grab these ones into .data too.

Hi Thomas,
This applies on top of mips-next or Linus' tree, so you may need to
rebase mips-fixes before taking it.
It's not for mips-next as it should go into this cycle as a [hot]fix.
I haven't added any "Fixes:" tag since these warnings is a result
of merging several sets and of certain build configurations that
almost couldn't be tested separately.

no worries, mips-fixes is defunct during merge windows. I'll send another
pull request to Linus and will add this patch to it.

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea. [ RFC1925, 2.3 ]
