    Revert "src.sys.obj.mk: Export OBJTOP"
    
    Unfortunately this results in make universe's environment, i.e.
    corresponding to the host, being used for every one of its sub-makes, so
    they're in the wrong place and trample over each other.
    
    This reverts commit 2b7c1402f96be2d2986738e32706dab7b5691ef0.
