Makefile: fix build if CDPATH is set in environment
Reported by Bjørn Forsman <bjorn.forsman@gmail.com>.
If CDPATH is set in the environment, cd <dir> will print the absolute path
of <dir>, causing various trouble (The most critical being BASE_DIR ending
up as <path> <path> which breaks basically everything).
Fix it by clearing CDPATH. Notice that export doesn't affect the environment
of $(shell ..) calls, so explicitly throw away any output from cd in the
BASE_DIR shell call.
