The AltiVec header file breaks boolean type:
error: incompatible types when initializing type
'__vector _bool int' {aka '_vector(4) __bool int'} using type 'int'
If __APPLE_ALTIVEC__ is defined, then bool type is redefined
and conflicts with stdbool.h.
There is no good solution to fix it for the whole project without
breaking something else, so a workaround is inserted in mlx5 PMD.
This workaround is not compatible with C++ but there is no C++ in DPDK.
