- add arch to .PKGINFO
- exit with success if package is not in arch

ap is a helper script to parse APKBUILD and calculate build time
dependencies.

see http://redmine.alpinelinux.org/issues/409

some awk's does not understand -F "\ " and treats that as special space

newapkbuild http://example.com/path/foo-1.0.tar.gz
will set
pkgname=foo
pkgver=1.0
source="http://example.com/path/foo-1.0.tar.gz"

Those are needed when linking to the lib and not during runtime.

Having those in the -dev package makes it easier to allow different
versions of same libs to be installed side-by-side.

based on patch from Andrew Manison. Thanks!

and make sure those options are passed over when building recursively

Based on patch from Andrew Manison. Thanks!

We want build the toolchain and build tools first

we need strip all '<>=' chars not only last

speeds up abuild -R a bit

To avoid confusing with the /etc/apk/cache

its needed for bumping pkgrel with sed and similar

so we can do: APK=apk.static abuild ....

we only enter dependencies dirs in same repo
