Apparently a recent Homebrew update now installs `gettext` into a
subdirectory under /usr/local/, requiring the CFLAGS/LDFLAGS to list
explicit directories _even_ when asking to force-link the `gettext`
package.

Likewise, the `msgfmt` tool is no longer in the `PATH`.

While it is unclear which change is responsible for this breakage (that
most notably only occurs on CI build agents that updated very recently),
https://github.com/Homebrew/homebrew-core/pull/53489 should fix it.

Nevertheless, let's work around this issue, as there are still quite a
few build agents out there that need some help in this regard: we
explicitly do not call `brew update` in our CI/PR builds anymore.
