Support for RaspberryPi 1

[milkpirate]

I have an old RaspberryPi 1 laying around and would like to use it for a project and it would really benefit from a slim Alpine image. Could you add a armv7 build as well?

Ok, added support by myself: #8

Raspberry pi 1 doesn't support ARMv7 but ARMhf.

Apply this patch:
