toplevel Makefile: accept arguments for host ./configure calls

Append $(HOST_CONFARGS) to ./configure scripts for 'host' applications.

This allows e.g. cross-compiling on an x86 build system for an OpenMoko
gta0x host, using an invocation such as:

$ make HOST_CONFARGS="--host=arm-angstrom-linux-gnueabi"
