configure with datadir outside of --prefix fails with meson

configure with datadir outside of --prefix fails with meson

[Anthony PERARD via]

Hi,

When we build QEMU while building Xen we do:
    ./configure --prefix=/usr/lib/xen \
                --datadir=/usr/share/qemu-xen \
                ...

But meson give an error:
  ERROR: The value of the 'datadir' option is '/usr/share/qemu-xen' which must be a subdir of the prefix '/usr/lib/xen'.

Would it still be possible to allow datadir outside of prefix or is it
going to be a limitation imposed by meson?

I can always change the call to configure but it would be nice not to
have to.

Thanks,

This appears to be enforced by meson. It ony allows certain dirs to
be outside the prefix.
