Yes, that is confusing.

OK, this is the step I was missing. Thank you.

Centos7.4 does not have those versions apparently, it is on automake
1.13 for example. I will have to build the toolchain by hand then and make sure it
is used over the system provided versions. That will take some time.
I will report back with the result.

Thank you so far !
