I usually use a 32bit chroot.

Use a 32bit chroot then symlink the result into the 64bit host.

ah ok thanks, can I copy the compiled mesa libs to the host directly?

hmm maybe I'll just create a ubuntu/debian chroot I suppose it's easier.

You can copy the libraries if you prefer. I did that for years but recently realized it wasn't necessary in my situation.

Studying the logs for a distribution would help.
Mesa logs for debian

The line below is essentially how you tell meson to build 32-bit.

Spoiler, click me

CC="gcc -m32" \
CXX="g++ -m32" \
\
meson

32-bit cross compilation is a mess in Debian at least, that's why I don't bother. The alternative is to use 32-bit VM, lxc container or chroot.
