You can get warnings if you _move_ the gettext-runtime directory so that it
becomes a sibling directory of 'gcc'. You should *not* get warnings if you
create a symlink, sibling of the 'gcc' directory, to the
gettext-20220620/gettext-runtime/ directory.

On macOS (with .dylib instead of .so) it would probably work.

However, AIX and HP-UX will not work, because (as I understand it) if you want
to have a binary, say cc1, which depends on libintl, then
  - the cc1 that accesses /usr/local/lib/libintl.$suffix
  - the cc1 that accesses /home/user/build/gcc-snap/gettext-runtime/intl/.libs/libintl.$suffix
must necessarily be different. You cannot just install the second one in
public locations, because it will have the wrong shared library filename
hardcoded into it. This is why on these systems, libtool has to rebuild
executables during "make install".

Anyway, you said that for GCC, the important case is to build libintl as a
static (non-shared) library.

Indeed, the option '--with-pic' (from libtool) has the same effect as
'--enable-host-shared'. If you can arrange to pass '--with-pic' instead
of '--enable-host-shared', I can revert the addition of the option
'--enable-host-shared' in gettext-runtime/intl from two days ago.

Are you aware that gettext.m4 already introduces the configure options
  --with-libintl-prefix[=DIR]  search for libintl in DIR/include and DIR/lib
  --without-libintl-prefix     don't search for libintl in includedir and libdir
