Actually this has been fixed in gettext some time ago.  The problem lies
on the following line:

configure.ac:24: AM_GNU_GETTEXT_VERSION([0.18.1])

This line is used by autopoint (called by autoreconf, called by
bootstrap script) to install the macros from that exact version.

The first warning can be removed simply bumping the version to 0.18.2,
which includes that fix.  The newer, the better, but that's the minimal
version change.

The warning left can be silly for Guix, as there are three different
translation domains in a single source code base, so the setup is
inherently more complex.  It is not a bad idea at all for a small/medium
size project to warn the missing po folder when the internationalization
is being set up, as gettext "enforces" the use of recursive make into
the it to get the translations targets; Guix does that not only
once, but twice, and another time with different tools and make rules
for the manual translation.

This point maybe worths a discussion in bug-gettext@gnu.org, at least
to give some way to disable it, but I had to clarify this
beforehand, as guix usage is not the common case and one warning
actually complies with our requested behaviour.

Happy hacking,
Miguel
