Warn about building a kernel with the wrong toolchain.

Idea from mrg@

Use OBJCOPY_STRIPFLAGS instead of STRIPFLAGS.

RISC-V support that works on QEMU with a single hart.

Thanks for Simon Burge for plic(4).

branches: 1.8.4;
Fix RV32 so it gets to the same point as RV64

Fixup kernel linking and provide a linker script with standard sections
and symbols

branches: 1.6.8;
Trailing whitespace

Misc changes in RISC-V.

Misc changes in RISC-V. Start changing the memory layout, too.

- Determine KERN_AS automatically depending on whether OPT_MODULAR is
set or not, in the same way as libcompat.

- Specify OPT_MODULAR in the port Makefile instead of KERN_AS.

Now, KERN_AS=library is used for kernels without module(7) for all ports.

OK christos

branches: 1.2.2; 1.2.18; 1.2.20; 1.2.22;
Use -mcmodel=medany to get PICish code.

Beginnings of RISCV kernel support. Note that the pmap support is not yet
committed and probably won't be for awhile. This is mostly preliminary
waiting for the supervisor specification to come out. Lots of missing pieces
but it mostly builds.
