firmware-brcm43xx-1.1-3-armv7h.pkg unknown makepkgopt keys

Hi,

I was cleaning up some old packages through "pacman -Sc" and I got the following warnings printed out:

[code]

I downloaded the package firmware-brcm43xx-1.1-3-armv7h.pkg.tar.xz and found the offending tags in the .PKGINFO file:

Looks like those makepkgopt keys at the end aren't in compliance. Nothing crazy at all, but it would be nice if it could be looked into for the next build.

Thanks.
