CHOST in makepkg.conf

[Snoop05]

Default CHOST on ARMv7 devices in ALARM:
$this->bbcode_second_pass_code('', 'armv7l-unknown-linux-gnueabihf')

In Gentoo its:
$this->bbcode_second_pass_code('', 'armv7a-hardfloat-linux-gnueabi')
and it also make more sense (at least to me)

Is it possible to change it, or it need to be like default because of archlinux, pacman and aur stuff?
