[Felix Singer (Code Review)]

Attention is currently required from: Felix Singer, Thomas Heijligen.

Hello build bot (Jenkins), Thomas Heijligen, Angel Pons,

Makefile: Fix dependencies for developerbox_spi

Note: This patch was backported from the master branch and it was
modified so that it can be applied on the 1.2.x branch.

The developerbox_spi programmer depends on bitbang SPI support. Thus,
fix that.
