Start support for the RISC-V 64-bit architecture developed by UC Berkeley. RISC-V is a new ISA designed to support computer research and education, and is now become a standard open architecture for industry implementations. This is a minimal set of changes required to run 'make kernel-toolchain' using external (GNU) toolchain. The FreeBSD/RISC-V project home: https://wiki.freebsd.org/riscv.

Add full softfloat and hardfloat support for RISC-V. Hardfloat is now default (use riscv64sf as TARGET_ARCH for softfloat). Sponsored by: DARPA, AFRL Differential Revision: https://reviews.freebsd.org/D8529 2016-11-16 10:21:32 -05:00			`.if ${MACHINE_ARCH:Mriscv*sf} != ""`

Correct an misunderstanding of MDSRCS. MDSRCS it intended to allow assembly versions of funtions with C implementations listed in MISRCS. The selection of the correct machdep_ldis?.c for a given architecture does not follow this pattern and the file should be added to SRCS directly.
