First, your find_files there is incorrect because of the OBJDIR=${dir}
bit.  If you actually want to assign OBJDIR inside find_files then you
need to wrap it in $(eval).

But from the way you use find_files in the $(foreach) I don't think
that's what you want.

If all you want is to figure out which directory (assuming that only one
exists) from a list of directories in OBJDIRS and store the result in
OBJDIR then you can just do:

OBJDIR := $(wildcard $(OBJDIRS))
