Indeed, following these instructions has solved my problem.
The trick is to use a file and the --cross-file meson parameter:
---
set -e
ARCHCFLAGS="-O2 -m32"
NUMJOBS="-j $(grep -c ^processor /proc/cpuinfo)"
NAME="32-mesa"
VERSION="19.1.4"
DIR="mesa-${VERSION}"
DESTDIR="/tmp/${NAME}-${VERSION}"
tar xvf ${DIR}.tar.xz
mkdir -pv ${DIR}/build
cd ${DIR}/build
export PATH="/usr/bin32:${PATH}"
export LD_LIBRARY_PATH="/lib:/usr/lib:/usr/local/lib"
export PKG_CONFIG_PATH="/usr/lib/pkgconfig:/usr/local/lib/pkgconfig"
export CFLAGS="${ARCHCFLAGS}"
export CXXFLAGS="${ARCHCFLAGS}"
export LDFLAGS="${ARCHCFLAGS}"
cat > cross_file.txt << EOF
