Is that really a problem? The drivers/Makefile has this:

obj-$(CONFIG_PARISC)		+= parisc/ 
And you just overrode that by forcing the build.  It's not even clear
we should refuse the build in that case; how would we know you don't
have a legitimate reason for the override?

If we conclude the use case is legitimate, that's not enough: the two
inner symbols are PARISC only but CONFIG_EISA isn't.
