    texi2pod.pl: add no-op --no-split option support [PR28144]
    
    Change 2faf902da ("generate single html manual page by default")
    added use of --no-split option to makeinfo. binutils reuses
    makeinfo options for texi2pod.pl wrapper. Unsupported option
    led to silent manpage truncation.
    
    The change adds no-op option support.

            * texi2pod.pl: Handle no-op --no-split option.
