[ Upstream commit 5ff90d427ef841fa48608d0c19a81c48d6126d46 ]
Commit b5e395653546 ("kbuild: install-extmod-build: Fix build when specifying KBUILD_OUTPUT") tried to address the "build" variable expecting a relative path by using `realpath --relative-base=.`, but this only works when the given directory is below the current directory. `realpath --relative-to=.` will return a relative path in all cases.
