[SLOF] [PATCH] libnet/Makefile: Define DHCPARCH in CFLAGS

[Murilo Opsfelder Araujo]

Some applications, e.g. https://maas.io/, trust on the dhcp code 93
option to reply the correct pxelinux.0 file according to client
architecture.

Today, dhcp.c is compiled without DHCPARCH, which causes it not to
send client architecture in the dhcp request, i.e. dhcpd server can
reply a pxelinux.0 binary that is not intended for client
architecture.

This patch makes sure client architecture is sent in the dhcp request.
