    kernel: Fix loading of gold-linked modules
    
    Kernel modules linked by gold differed from those modules linked by ld.bfd in that
    the .note.GNU-stack section on ld.bfd were set as size "1" whereas on gold this section
    was size "0".  The object loading code was not set handle sizes less than 1, causing
    module loading failure.
    
    The fix of ensuring the smallest alignment to be zero by checking for -1 is required
    over FreeBSD's technique of continuing if the section size is zero because an internal
    check causes a "lost progbits" panic when FreeBSD's method is used.
    
    This adjustment should enable a fully functional world and kernel to be built by gold
    linker using WORLD_LDVER=ld.gold in make.conf.  Before this, only the world worked;
    the kernel could not be booted.
