OK, doc really warn about using AC_RUN_IFELSE while cross compiling.

In the third one [2] there is libnuma installed (ibnuma-dev package, so configure works:
/* Define to 1 if you have libnuma and it's headers version >= 2 installed. */
#define HAVE_NUMA_V2 1
The other two don't.
But all these 3 cross compile builds are build in-tree.
I tested to build cross compile out tree in our project and it's really broken.
Thanks for a bug report, I'll fix it.


Kind regards,
Petr
