    libgcc: Quote variable in Makefile.in
    
    If the xgcc executable has not been built (or has been removed by 'make
    clean') then the command to print the multilib dir fails, and so the
    MULTIOSDIR variable is empty. That then causes:
    /bin/sh: line 0: test: !=: unary operator expected
    
    We can avoid it by quoting the variable.
    
    libgcc/ChangeLog:
    
            * Makefile.in: Quote variable.
