Subject: Remove the toolchain in riscv-tools

The toolchain pointed to by riscv-tools hasn't been maintained for more
than a year now.  This pointer was necessary when we had out-of-tree
ports of the various toolchain components, but now that everything is
upstream toolchains can be obtained via dozens of standard mechanisms.
Having a broken toolchain so publicly visible causes everyone headaches,
so unless someone wants to step up and maintain this I'm going to remove
it.

In order to keep the Travis running, I've gone ahead and used
crosstool-ng to build a toolchain.  This should be a lot more reliable
than the old riscv-gnu-toolchain based approach.

Subject: Expect 11 debug test failures

We need a GDB with RISC-V XML target description, which isn't in a release
yet, so isn't available through crosstools.

Additionally, the riscv-tests/debug scripts will need to be updated to
handle different GDB output when printing FP registers.
