YAXT Version 0.6.1 available

This is a bug-fix release that only

adds a file missing from the distribution archive (but is only needed when time-stamps get changed)
fixes a problem when ifort or icc was used with the -diag-disable option having an argument as next command-line argument instead of separated by an equals sign
fixes needed if autoreconf is performed with automake 1.16
