bug#67891: automake-1.16i doesn't build on Solaris 10 sparc

[Paul Eggert]

Here are the symptoms. But now that I look into it, I see the 
automake-1.16 build fails with the same symptoms. So I assume this is 
low priority.

  GEN      doc/automake-1.16.1
help2man: can't get `--help' info from bin/automake
Try `--no-discard-stderr' if option outputs to stderr
*** Error code 255
The following command caused the error:
echo "  GEN     " doc/automake-1.16.1;:; HELP2MAN_NAME="Generate 
Makefile.in fi\
les for configure from Makefile.am"; export HELP2MAN_NAME;
