    mk: Mark buildenv .NOTMAIN
    
    This file is one of a handful that can be included at the top of a
    Makefile (via src.opts.mk).  Therefore, all the targets it defines
    must be marked .NOTMAIN so they don't accidentally become the default
    target of the Makefile.
    
    Fixes:          cf5f0744cd1d ("Add .NOTMAIN to guard targets")
