Wrapper to have make use the correct cross compiler

armmake

#!/bin/ksh
MACHINE=armv7
MACHINE_ARCH=arm
MACHINE_COMP=armv7
VERSION=1.0
#this is true for most archs
MACHINE_CPU=${MACHINE_ARCH}
TARGET=${MACHINE}

HOST=$(uname -m)

export MAKEOBJDIR=obj.${HOST}.${MACHINE}
export HOST MACHINE TARGET

ABI=-gnueabihf
CROSSDIR=/usr/cross/${MACHINE}
CROSS=${MACHINE_COMP}-unknown-bitrig${VERSION}${ABI}
PATH=$PATH:${CROSSDIR}/usr/${CROSS}/bin:${CROSSDIR}/usr/bin

export BSDOBJDIR=${CROSSDIR}/usr/obj

MACHINE=${MACHINE} \
MACHINE_ARCH=${MACHINE_ARCH} \
MACHINE_CPU=${MACHINE_CPU} \
CROSSDIR=${CROSSDIR} \
CC=${CROSS}-clang \
CPP=${CROSS}-cpp \
CXX=${CROSS}-clang++ \
AS=${CROSS}-as \
LD=${CROSS}-ld \

make \
MACHINE=${MACHINE} \

"$@"

To run this on OpenBSD, replace:
MACHINE_COMP=arm
VERSION=5.8
ABI=
CROSS=${MACHINE_COMP}-unknown-openbsd${VERSION}${ABI}
CC=${CROSS}-cc
CXX=${CROSS}-c++ \
