so far only option avaiable is !strip, which disables stripping of binaries.

The -r option will only install deps from system repo and fail if any is
missing.

The -R option will parse the aports tree and try build the missing packages
and then install the newly built package.

set default repositories

abuild [-c] -n PKGNAME[-PKGVER]
creates a directory with new APKBUILD. If -c is specified will sample init.d,
conf.d and install script be copied as well.

Read the version from .alpine-release on media. Also display the init
script version.

also create the symlink for kernel modules

This reverts commit fe7da984.

Conflicts:

	abuild

by sourcing the functions.sh after abuild.conf

I'm not sure if we really want this

This will let user specify a directory where the repositories are.
Setting REPODEST will override PKGDEST.

try deal with dependencies for makedepends

Example.
foo-dev is a makedepends which depends on foo. We need to install foo before
we can install foo-dev.

The way we deal with thi here is hackish and should be replaced by adding
all built packages to an abuild repository or similar.

the dependency repo tells apk index that dependencies are found
in another repository.

now its possible to build alpine iso with uncommitted developer abuild apk.
