So, for the records, in cae you missed the IRC discussion:

  - our gettext-gnu package has: HOST_GETTEXT_GNU_SUBDIR = gettext-tools
    so only the gettext-tools sub-directory is configured and built

  - gettext-tools need libtextstyle, but that is not getting configured
    nor built

So we have three options:

  - add hooks to configure + build libtextstyles as a pre-configure hook
    in gettext-gnu, and install it in a pre-install hook,

  - add a separate package for libtextstyle,

  - revert to building the whole of gettext.

Adam did some timings with BR2_JLEVEL=4, and he got:

  - just getext-tools:      38.86s user 22.13s system 124% cpu 49.035 total
  - just libtextstyles:     40.78s user 14.57s system 146% cpu 37.817 total
  - whole of gettext:       203.18s user 122.87s system 161% cpu 3:22.39 total

So, the whole of gettext is still ~4x the time to build the tools and
libtextstyle. This is not acceptable...

I think hacking the build of libtextstyles with hooks is not gonna fly
far either.

So we're back at a separate package as the only viable solution, I'm
afraid.

Does that make sense?

Of course, we need to write that down in a commit log somewhere... ;-)

Yann E. MORIN.
