I just got mesa out of the way by renaming 
/usr/lib/arm-linux-gnueabihf/mesa-egl to something else.
So now it's using the armhf libs provided by Tom/AllWinner (checked with 
ldd), but it fails to open the UMP driver:

./es2_info
UMP: ump_arch_open() failed to open UMP device driver
*********************************************************************
ERROR: In file: src/base/common/mem/base_common_mem.c  function: 
initialize_memory_system()   line:1521
Could not open UMP memory system. Shutdown.

Error: eglInitialize() failed

I got mesa-demos source code (apt-get source mesa-utils-extra) and I 
could not find base_common_mem.c anywhere, and objdump indicates 
initialize_memory_system is a locale function inside libMali.so.
