[dpdk-dev] [PATCH v3] build: meson set toolchain info during config init

[Pavan Nikhilesh <pbhagavatula@caviumnetworks.com>]

Meson identify toolchain using cc.get_id and set RTE_TOOLCHAIN,
RTE_TOOLCHAIN_X during initializing dpdk_conf so that it can be used by
both x86 and arm.

Suggested-by: Bruce Richardson <bruce.richardson@intel.com>

 v3 Changes:
 - Use a generic way of setting toolchain instead of chaining conditions.(Bruce)

 v2 Changes:
 - Use get_id for identifying compiler instead of checking for compiler defines
 manually.(Bruce)
