Log message:
net/dhcpcd: Pass --build and --host for cross-builds.

This custom configure script may not be quite compatible with
GNU_CONFIGURE=yes, but it's compatible enough for GNU --build and
--host options.

No change to native builds -- conditional on USE_CROSS_COMPILE
(though it ought to be harmless even if unconditional).
