[OE-core] "--disable-werror" versus "--disable-Werror"?

[Robert P. J. Day]

  apparently another gcc-5.0.0 issue(or maybe not), but my build of
core-image-minimal for qemux86 now fails thusly trying to build
elfutils-native:

| cc1: all warnings being treated as errors

  since all warnings are being treated as errors, i did a quick check
to see how to disable that option on a per-recipe basis and *thought*
i could just add the following line to local.conf:

EXTRA_OECONF_pn-elfutils-native = "--disable-Werror"

but that didn't do it.  but there's more.

  i did a "grep" just to see how other recipes were doing it, and i
saw a mixture of "--disable-werror" versus "--disable-Werror", and
this web page which suggests that only one of those forms is correct:

http://patchwork.openembedded.org/patch/23361/

but feel free to search for yourself to see.

  in any event, what *is* the proper local.conf fix to disable this
option on a per-recipe basis?
