Laurent, All,

OK, so the bug is already visible here : see how the output contains make
messages around
the version value.

However, this is very strange, because:

1. we're telling make to not print those emssages: --no-print-directory -s
2. it is entering and leaving different directoriee: Entering directory
'/home/buildroot'
   but: Leaving directory '/home/buildroot/output/build/linux-linux4sam_6.2'

So I suspect a weird corner-case bug in make... 

Oh, by the way, top-level parallel build is not 100% supported, though, and at
the
very least, requires that you enable BR2_PER_PACKAGE_DIRECTORIES.

Regards,
Yann E. MORIN.
