If you put your cross file in ~/.local/share/meson/cross then you could just do

meson --cross-file=meson-32-cross --buildtype=release --prefix=$PWD/build/32/install -Ddri-drivers=i965 -Dvulkan-drivers=intel -Dgallium-drivers= -Db_ndebug=true -Dglvnd=true build/32

I think Eric Engstrom also landed is if-debug patches, so ndebug is by default
only enabled for debug and debugoptimized builds now. I think.
