    automake: avoid unnecessary use of \K.
    
    This fixes (part of) https://bugs.gnu.org/67891
    and follows up on https://bugs.gnu.org/55025.
    
    * bin/automake.in (generate_makefile) <posix>: avoid use of
    \K when removing comment and blank lines before a .POSIX target,
    since Solaris 10 has perl 5.8.4, and \K was added in 5.10.
