We check if noarch is properly set

Some .so files have a rpath where to look for the needed .so. When tracing
package dependencies we also have a look there.

This should fix problem when the .so is not in standard location, /usr/lib
or /lib. (for example freeradius plugins)

While here we also reorganize things so we only call apk info --who-owns
once for each package instead of once for each needed .so. This should
speed up things when there are many needed .so files.

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

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

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

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

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

When building with crosscompile to bootstrap a new target it might
be handy to not include the dependencies etc.

This avoids confusion when abuild picks dependencies from testing
when building main.

This option is normally used for bootstrapping a build env. Chances are big
that apk-tools is not around.

to make life easier for volatile packages

override with -F

We also make sure we source the APKBUILD when we are in the directory
holding the APKBUILD file. Some of the packages sources others
with relative references. (for example kernel 3rd party packages)

try keep code in abuild cleaner by moving out creation of new apkbuild
to separate script.

prepare is run before build(). this allows uses to do patching before
configuring and building in a separate step.
