[Buildroot] [git commit] package/dhcp: build internal bind tool gen for host (not target)

[Arnout Vandecappelle]

commit: https://git.buildroot.net/buildroot/commit/?id=7c814fe9b2fe84d7e294d511c3d62319bcae3281
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Building gen tool of the internal (bundled) bind needs to be for host, not target
Switch to use internal build in commit 0c8dd6ebd656e06cf99a63eb93343715f4853503
overlooked this.

Building dns library in /home/autobuild/autobuild/instance-13/output-1/build/dhcp-4.4.2-P1/bind/bind-9.11.14/lib/dns
/bin/sh: line 1: ./gen: cannot execute binary file: Exec format error

Thus, we need to set not just CC, but also CFLAGS etc. otherwise the
target CFLAGS etc. will be inherited from top-level configure.
