Commit b5e3956535 ("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.
