`make man` no longer works due to presence of man directory in source

[Sharpie]

Because there is a man directory in the GDAL 1.9.0 source, make man does not work:

  bash-3.2$ make man
  make: `man' is up to date.

Because man exists as a directory, make assumes the "target" has been built and does not execute the build steps for the rule.

Either:

• The man directory must be removed from the source distribution.

• man must be marked as a .PHONY target in GNUmakefile. This is probably a good idea in general.

It appears this directory is created in the dist files because mkgdaldist.sh does a "make docs" which creates it but does not populate it. If the man pages are decent we should likely distribute them and ensure make install installs them as well as adding the .PHONY suggested.

I'll look into this.

Replying to warmerdam:

That would be awesome. GDAL has a pile of dependencies---getting rid of Doxygen without sacrificing manpages would be very nice.

Grr. I prepared nice detailed notes on the changes I've applied, but the damn chrome undo/redo bullshit ate it and I won't rewrite it.

r24262, r24263, r24264, r24265, r24266, r24267

core changes backported to 1.9.

man page production should be smoother in the release process - should see this in 1.9.1.
