the explanation (which I seem to keep forgetting forever) is the
two-phase evaluation of makefile and so-called deferred expansions:

With v6 it is possible to compile ft2232_spi and usbblaster_spi
independently. The only thing that does not work is stuff like
make distclean ; make CONFIG_FT2232_SPI=yes CONFIG_USBBLASTER_SPI=no ; make CONFIG_FT2232_SPI=no CONFIG_USBBLASTER=yes
because of the enum programmer, but that is not specific to this
programmer, so I have committed ~this version in r1658 eventually.

Thanks Kyösti for pushing and thanks James for the initial version of
the patch!
Kind regards/Mit freundlichen Grüßen, Stefan Tauner
