[Buildroot] [PATCH 3/4] toolchain: introduce BR2_TOOLCHAIN_HAS_RESOLVER
Guido Martínez

Fri Jun 26 17:33:21 UTC 2015
Add a Kconfig option specifying if the toolchain supports name resolving
(or at least has stubs for it) so we can disable packages that depend on
that (or they would fail to link). For now, only disable the 'nslookup'
tool from BusyBox if there's no resolver support.
For now, every toolchain supports name resolving.
