No -DHAVE_LIBNUMA=1 was passed to the source compile (and the
global include/my_config.h wasn't used).

This also is Linux only so corrected the cmake macro.

Fixed indenting in cmake macro.

Removed NUMA defination from include/my_config.h as its only
in the storage engine.

Thanks Elena Stepanova and Vladislav Vaintroub for the detailed
list of bugs/questions.
