[PATCH 1/3] ARC: allow to overide default mcpu compiler flag

2020-05-29 Thread Eugeniy Paltsev
By default we set -mcpu=xxx compiler flag depending on the CPU ISA version. It's good starting point, however that may be not enough as for some platforms we may want to use some specific 'mcpu' options for better optimization or to workaround HW issues. We are going to use this option for HSDK-4x
