Marcel Moolenaar ba6a2bb365 Add --no-warn-mismatch to ld(1) when linking binary files into 
ELF files. On ia64 the ELF header contains information about
characteristics of the machine code and ld(1) needs that to
determine whether input files are compatible for linking. To
this end non-ELF files are not supported by binutils on ia64.
However, the resulting ELF file seems to be correct despite the
warnings and the non-supportedness of non-ELF files and it
appears enough to unbreak the build of firmware(9) files on ia64
by simply supressing the warning.

# From: @(#)bsd.prog.mk 5.26 (Berkeley) 6/25/91
# $FreeBSD$
#
# The include file <bsd.kmod.mk> handles building and installing loadable
# kernel modules.
#
#
# +++ variables +++
#
# CLEANFILES Additional files to remove for the clean and cleandir targets.
#
# EXPORT_SYMS A list of symbols that should be exported from the module,
# or the name of a file containing a list of symbols, or YES
# to export all symbols. If not defined, no symbols are
# exported.
#
# KMOD The name of the kernel module to build.
#
# KMODDIR Base path for kernel modules (see kld(4)). [/boot/kernel]
#
# KMODOWN Module file owner. [${BINOWN}]
#
# KMODGRP Module file group. [${BINGRP}]
#
# KMODMODE Module file mode. [${BINMODE}]
#
# KMODLOAD Command to load a kernel module [/sbin/kldload]
#
# KMODUNLOAD Command to unload a kernel module [/sbin/kldunload]
#
# MFILES Optionally a list of interfaces used by the module.
# This file contains a default list of interfaces.
#
# PROG The name of the kernel module to build.
# If not supplied, ${KMOD}.ko is used.
#
# SRCS List of source files.
#
# FIRMWS List of firmware images in format filename:shortname:version
#
# FIRMWARE_LICENSE
# Set to the name of the license the user has to agree on in
# order to use this firmware. See /usr/share/doc/legal
#
# DESTDIR The tree where the module gets installed. [not set]
#
# +++ targets +++
#
# install:
# install the kernel module; if the Makefile
# does not itself define the target install, the targets
# beforeinstall and afterinstall may also be used to cause
# actions immediately before and after the install target
# is executed.
#
# load:
# Load a module.
#
# unload:
# Unload a module.
