Afaics, there is no ARM target with WFE enabled and we lost ability to
enable WFE support with removal of the make build system.
$ git grep RTE_ARM_USE_WFE
config/arm/meson.build: ['RTE_ARM_USE_WFE', false],
lib/eal/arm/include/rte_pause_64.h:#ifdef RTE_ARM_USE_WFE
How did you enable WFE to test this series?
