tools/missing-macros: add symlinks to makeinfo

There are other wrapper scripts released with makeinfo like texi2pdf which
are required by the build prerequisites of some tools, and have a similar
purpose and usage.

Let the makeinfo perl script handle all of these cases.

It's worth mentioning that "texi2any" is the actual program and "makeinfo"
is one of it's aliases. From upstream GNU:

  makeinfo: texi2any
	rm -f $@
	-$(LN_S) texi2any $@
