failures on mips64el / s390x with openresty's version of luajit

[kapouer]

Hi,

luajit in debian/trixie (which will come after bookworm, the current stable) has moved to openresty's version. It supports several architectures: amd64 arm64 armel armhf i386 mips64el mipsel s390x powerpc

The lua-vips debian package, however, fails on two of those, when running the tests.

Build logs: mips64el s390x

which can be compared to a successful build: armhf

This may very well be a luajit bug, but I'm starting it here now :)
