Is it possible to override makepkg.conf settings on the command-line ?

Simple question, hopefully I've just missed the answer while googling this.

To cross-compile an ARM package on my x86 box, I have to change the value of ${CARCH}. The only way I've been able to do this is to modify its setting in /etc/makepkg.conf. I'd like to be able to just specify it on the command-line along with my other variables; something like:

CROSS_COMPILE=/opt/arm-bcm2708hardfp-linux-gnueabi/bin/arm-bcm2708hardfp-linux-gnueabi- ARCH=arm CARCH=arm makepkg -s

However, the setting of CARCH like that is ignored. All other variables have the desired effect. Is it not possible to set makepkg variables on the command-line ?

If I have this completely wrong and I should be doing it another way, I'd appreciate some guidance. But, by that, I don't mean build on arm with distcc because I have already done that and it takes over three hours versus under ten minutes for the above method which, apart from needing to modify makepkg.conf, works great

You could specify an alternate configuration file instead of the default one.

Subject: [PATCH] makepkg: add support for CARCH environment var

Add support for overriding configuration in /etc/makepkg.conf and
~/.makepkg.conf by setting the environment variable CARCH similar to
how SRCDEST and PKGDEST behave.

Yes @fukawi2 that patch does exactly what I want. I have voted for it and hope it makes it into the official package. Thanks.
