This patch (passing --with-slibdir) doesn't actualy fully work
(when cross-compiling to i686-linux-gnu from a x86_64-linux),
as libstdc++ is not installed in the right place
(and other stuff like libusan, but those are less critical IMHO).

I sent a more complete (and hackier) patch as part of the
patch series for implementing cross-compilation in Meson
(not really the right place, I know, but it's hard to test
cross-compilation when the cross-compiler is broken),
see [PATCH v3 core-updates 36/37: Fix cross-compiler for i686-linux-gnu]
(https://issues.guix.gnu.org/49025>.

I'll send a mail to bug#49025 asking people to respond about
that patch at bug#48913, to keep things separate.

I'll test whether aarch64-linux-gnu and armhf-linux-gnueabihf
have the same problem and whether the patch (from bug#48913)
addresses it.

Greetings,
Maxime.
