If makeinfo is not found in the system then the missing
script is used to warn the user.

Before commit e30465112ed4c6320dd19107302057a5f7712cf2 the missing
script returned 0 after printing the message.

Now, missing return 127 (command not found) to the Makefile and
the build fail.

As suggested [1], add a new option to disable the documentation.

This patch is untested since I can't regenerate the configure script
due to autoconf version mismatch.

configure.ac:34: error: Please use exactly Autoconf 2.64 instead of 2.69.
