[Buildroot] [PATCH] dhcpcd: unavailable for bfin and fix another bug

[Gustavo Zacarias]

dhcpcd needs a toolchain with getifaddrs support which the current
blackfin toolchain lacks. Fixes:
http://autobuild.buildroot.net/results/f4dd9ca2774bc89e6f976d75a13190d8a1e457f3/

This is not detected by dhcpcd's configure because it's being called
with default (non-cross) CC and other variables.
Thus pass TARGET_CONFIGURE_OPTS to configure to fix this.
Fixes another build failure i've encountered where the host has very
modern headers and dhcpcd tries to use the latest features which the
cross toolchain lacks.
