RISC-V: Build Infastructure
This patch lays out the top-level orginazition of the RISC-V port.  It
contains all the Implies files as well as various other fragments of
build infastructure for the RISC-V port.  This contains the only change
to a shared file: config.h.in.

RISC-V is a family of base ISAs with optional extensions.  The base ISAs
are RV32I and RV64I, which are 32-bit and 64-bit integer-only ISAs, but
this port currently only supports RV64I based systems.  Support for
RISC-V lives in in sysdeps/riscv.  In addition to these ISAs, our glibc
port supports most of the currently-defined extensions: the A extension
for atomics, the M extension for multiplication, the C extension for
compressed instructions, and the F/D extensions for single/double
precision IEEE floating-point.  Most of these extensions are handled by
GCC, but glibc defines various floating-point wrappers and emulation
routines as well as some atomic wrappers.

We support running glibc-based programs on Linux, the support for which
lives in sysdeps/unix/sysv/linux/riscv.
