net/mlx: fix build with make and recent gcc

Browse Source 
With VERBOSE=1, this error was seen in debug mode with gcc 9.1:

__aligned_u64 driver_data0;
^
1 error generated.

As a result, buildtools/auto-config-h.sh was not generating
a correct autoconf file, so the compilation was generating such error:

fatal error: redefinition of 'mlx5_ib_uapi_flow_action_packet_reformat_type'

It is fixed by disabling -pedantic option when calling auto-config-h.sh
from the makefile-based system.
