On x86 platforms, max lcores are limited to 128 by default.
On AMD EPYC processors, this limit was adjusted for native builds in
the commit acb34af951cf ("config/x86: increase lcores number for native
AMD EPYC")
As agreed earlier in mailing list, this patch adjusts the limit
for specific AMD EPYC target/cross builds.
