[flashrom] [PATCH] Makefile cleanup

[Carl-Daniel Hailfinger]

We already have NEED_PCI in the Makefile to link in PCI support. Add
NEED_SERIAL and NEED_NET to decouple individual drivers from compilation
and linking decisions.
Move libgetopt from a DOS+PCI dependency to a DOS dependency to fix
linking on DOS if no driver requiring PCI is enabled.
