The issue is that the EAL parsing code is performed during rte_init(), which
is exactly what this function tries to avoid - initializing EAL before a primary
process starts.

I looked at changing the EAL parsing to come before rte_init(), and considered
adding a minimal parser for --file-prefix. Both routes seem a bad solution,
either for complexity or code-duplication.
