[Nano-devel] [PATCH] build: don't explode when 'makeinfo' is missing

[Benno Schulenberg]

It is not possible to define info_TEXINFOS conditionally.  :|

So... build nano.info "manually" and forget about the pdf and dvi
targets.  This has the additional advantage that a 'make clean'
doesn't remove the nano.html file, and as 'makeinfo' is deadslow
nowadays, this saves a couple of seconds on a clean build.

This fixes https://savannah.gnu.org/bugs/?49969.
