Yes. The modification was based on the assumption that Make target
names _and_ board config file names could be used as valid C
identifiers, which is obviously not the case.

Of course we could rename the respective Make targets and
directories, but this is (1) some effort and (2) requires negotiation
with the respective board maintainers, as documentation, build
scripts and other things may be effected by such a change.

Alternatively, we could filter out such problematic characters, but
then again we have to check which side effects this may cause.

All together: this patch needs a lot more thinking and more careful
testing.

I tend to revert it.

Best regards,

Wolfgang Denk
