The existing macros are fragile and expect local variables with a
certain name. Fix this by defining them as functions with default
implementation in a new header dl-runtime.h which arches can override
if need be.
This came up during ARC port review, hence the need for argument pltgot
in reloc_ind

As prior patches we do not use DCO, but rather copyright assignment.

Oooops, this one is duplicate and should be dropped.

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

This initial port adds support of ARC HS4x/HS4xD Development Kit board with some
basic features such serial port, USB, SD/MMC, SPI flash, Ethernet and others.
The HSDK-4xD board has much in common with its predecessor - HSDK board.
However HSDK-4xD has some differences in comparison with its prede
