bootstrap: Clean up use of gettextize

[mkoeppe]

See discussion at
Homebrew/homebrew-core#53192

Instead of using gettextize at bootstrap time, we just vendor the files m4/iconv.m4 and config/config.rpath in the source tree.

This is done by using gnulib: gnulib-tool --import iconv (and ignoring all the other files that it is offering us).

(from dimpase on #27823)

Bruno Haible says on bug-autoconf that one should use gnulib's iconv module to install config.rpath etc. Indeed,

gnulib-tool --import iconv

will install config.rpath into config/ (among with other things that probably can be ignored).
So this is something to try in order to get rid of the hacky install_config_rpath() in comment:18

Unfortunately, gnulib is not present on homebrew (https://repology.org/project/gnulib/versions), so we should not try to use it in the bootstrap phase... Of course we can just commit the generated file -- it probably does not change so often.

any reason for gnulib not being on homebrew?

(anyhow, I'm testing this now).

upstream says: just use git to get gnulib, as there is nothing to build.

Hmm, yes, we can in principle have gnulib installed as a git submodule...

That's what I did, and I committed the result.
