    autogen.sh: avoid sed error "read error on stdin: Is a directory"
    
    The following line in autogen.sh was causing an error:
    
    macrodirs=`sed -n -e 's,AM_ACLOCAL_INCLUDE(\(.*\)),\1,gp' < $coin`
    
    "sed: read error on stdin: Is a directory"
    
    This line is supposed to look for occurrences of this macro
    in the configure script, however the $coin variable contained
    the value ".", not "./configure.in", so the $macrodirs variable
    was not being populated. After fixing this, however, the
    $macrodirs variable is still empty (because we don't use
    AM_ACLOCAL_INCLUDE in 'configure.in') but at least we removed
    the red herring caused by the unique real usage of the $coin
    variable (it is also used to extract $dr, which is the dirname
    of $coin, which maps to "." regardless if $coin is "." or
    "./configure.in", so everything keeps working as before).
