[PATCH] Add support for RISC-V

2018-04-19 Thread Andreas Schwab 
This implements initial support for the RISC-V architecture.  It has
been tested with qemu linux-user emulation
,
with the following unresolved issues

In addition, all tests that use ptrace are failing as linux-user
emulation does not implement it.

There are no regressions for a x86_64 build.
