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

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

not used anymore

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

basically remove dev packages

makes it easier to support parallel builds on non gnu make system

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
