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.

Thomas.
