    build-self: Let HOME pass through the execution environment.
    
    This is a followup to 48d498c2c3984784336b27ba5e261319f3ac6a3a, which
    introduced a typo (missing '->' in 'mlet'.)
    
    Fixes <https://bugs.gnu.org/35623>.
    Reported by Karrick McDermott <address@hidden>.
    
    * build-aux/build-self.scm (build): Add 'getenv' and 'setenv' calls for
    HOME.
