GCC GNAT 14 issue with gettext

[Dmytro Kazankov <dkazankov%NetBSD.org@localhost>]

Hi!

I have a problem with a package that I want to add to pkgsrc.
My problem is specifically with wip/gcc14-gnat, but the same problem exists with lang/gcc14, although it is 
currently hidden there.
wip/gcc14-gnat has NLS option and uses libiconv and gettext-lib for this.

The problem itself:
The current version of the package builds fine, but binary package does not install in a clean environment with 
message

pkg_add: Missing required library: /usr/pkg/lib/libintl.so.8

The immediate cause of the problem:
That's because the binaries are linked against the pkgsrc version of libintl (and libiconv), but there is no 
dependency on neither libiconv nor gettext-lib in the binary package deps, thus the builtin (base system's) 
versions only are required.
Of course there is also no full dependencies on libiconv and gettext-lib in build log:

===> Skipping vulnerability checks.

The origins of the problem:
GCC 14 raised requirements for libiconv and libintl libraries versions, thus, the version from the base system no 
longer satisfies requirements, but the version from pkgsrc satisfies.
Therefore, NLS in gcc14 package (and gcc14-gnat) went down - although it is turned on in the package, it is turned 
off implicitly at the "configure" stage 2 ("use NLS... no").
As a result, the gcc14 binary package no longer contains a share/locale folder, unlike gcc13, but this is hidden 
by the fact that gcc packages do not provide a PLIST.
gettext-tools/msgfmt-desktop.mk was added in gcc14-gnat to fix this problem, but it resulted in the problem 
described at the beginning.

Does anyone have any suggestions on how to fix the problem, please?
Except for the obvious option of "turning off NLS" - I would like to solve the problem, rather than hide it.

Thanks,
Dmytro.
