    autogen: add shortcut for building with clang
    
    For a while I have been cleaning up warnings when building with clang.
    There are currently only two sources of warnings left: Wcast-align and Wgnu.
    I am not convinced that fixing up those up is feasible so I run with them
    disabled to spot regressions. E.g. clang is a bit more strict wrt to unused
    variables with the cleanup attribute and I have fixed a number of those since.
    
    Like the other options in autogen.sh I have a shortcut for clang as well. I use
    'l' for llvm.
