[Buildroot] [git commit] package/libnss: fix build on powerpc

[Arnout Vandecappelle (Essensium/Mind)]

commit: https://git.buildroot.net/buildroot/commit/?id=f3c9d992cf73acafca96c6186428be3593457dde
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Set NSS_DISABLE_CRYPTO_VSX which is available since version 3.64 and
https://github.com/nss-dev/nss/commit/9dab43371d4d924419523e18ba84f02804880533
to avoid the following build failure on powerpc:

cc1: warning: '-mvsx' requires hardware floating point
cc1: error: '-mno-vsx' turns off '-mcrypto'

Passing this option on non-powerpc is harmless.
