[Buildroot] [PATCHv2] package/libbsd: not available for ARC

[Yann E. MORIN]

libbsd has explicit, hard-coded checks about the architectures it can
work on, and ARC is not one of those.

We did not notice so far, because we only recently added support for
glibc on ARC (and only for a single variant) in 0633eb58a291 (toolchain:
add glibc support for ARCv2).

Add an explicit exclusion on arc.

Fixes:
