I copied the conditional from config/linux.h but I admit I don't fully understand when the macro is defined.
AFAICT it's done in config.gcc, for a limited set of targets.
Should I still remove it from targhooks.c?
That is compiled for all targets, not just for those which define the macro, so yes.
Yes, the glibc and uclibc hooks are the same. I don't know what the convention is for these target hooks (i.e., whether they are expected to be duplicated across targets even if they are the same to reduce the risk of breaking one target as a result of changing another, or whether duplication should be avoided even at this risk). From your comment it sounds like it should be the latter and I'm okay with that.
There's arguments for both. In this particular case I don't see a strong reason not to have a general hook available.
