[arch-general] problem compiling for i586 with new makepkg

There is a problem with compiling with CHOST="i586" with the new pacman/makepkg. It simply refuses with the message: pkgname is not available for the 'i586' architecture. Note that many packages may need a line added to their PKGBUILD such as arch=('i586'). To edit each and every PKGBUILD for each and every package and every update appears like quite a big work. And since I could not find any option to turn that "feature" off, or any hook to SED it in, I just commented it out in makepkg. What was the thought with this? The -w option is also taken away from makepkg. Why? (I found the alternate solution, but still) Karolina
