Subject: [PATCH] buildsystem: remove grep from PKG_ARCH check

More efficient, slightly more functional.

Can be a space delimited list of architectures.

Architectures to be excluded can be specified with !ARCH.

Allows "any !arm" to be interpreted as "any arch, but not arm".

Blank/undefined is equivalent to "any".
