another alternative is to use realpath:
-GPIODIR := ../../../gpio
+GPIODIR := $(realpath ../../../gpio)

btw, this commit:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=51c6bd7cbe0366b642d8ac90d98739c39ab091a9
should be reverted once the build error is addressed because they
shouldn't have been there in the first place due to lack of trailing
slash in the path.
