Hi,
Gentle remainder for review.
Thanks,
Reshma
The GCC 4.9 -march option supports the intel code names for processors,
for example -march=silvermont, -march=broadwell.
The RTE_MACHINE config flag can be used to pass code name to
the compiler as -march flag. Also old gcc versions compatibility code
for the intel platform is removed from
mk/toolc
