this is just a wrapper script. the real stuff happens in alpine.mk

also link mkiso to use the makefile

tries to get correct dependencies for modloop, initramfs and iso
so minimum amount of work is required for rebuild.

Also any /usr/share/gettext dir.

This reverts commit b27a6f47.

this avoids rebuilding those unless its needed

it was a bad idea since it messes up symlinks

- Added option -i, to install a given build target after successful build.

- Parse all APKBUILDs and use awk to calculate a dependency graph. Then
  build the package and use -i to install the needed dependency.

- Uninstall all build dependencies after package is built (unless -i given)

- Automatically add binutils gcc make patch uclibc-dev as deps

- set boot prompt timeout to 2 sec
- remove unused boot parameter
- move test.gz to /boot subdir

try also mount modloop during boot and run a second pass hardware
detect.

those should probably go to a separate package but I put them here for now
