Makefile: unexport O
After bee5745ccc2 ("Makefile: don't depend on the umask"), any use of "make O=<dir>" would leak $O into the enviroment for submakes, and it's inherited by package makefiles. Some package makefiles have protections to make sure they don't use the value of $O if it comes from the enviroment (Linux), but some don't (uClibc). This caused build failures when using a different output dir. Fix this by unconditionally unexporting the O variable, since we never need to have it set in the environment for packages, it should be only internally used by BR.
