mips64-unknown-linux-gnu-gcc (crosstool-NG git+7f1c646) 4.9.0
eglibc 2.15

But this does indeed appear problem with the kernel and not the
toolchain.  Sadly I can't opt for softfloat with this.  I'm going to be
trying to look at the patch that Markos identified; it looks like it may
have mixed up MIPSInst_RT and MIPSInst_FD in a copy-and-paste.
(Guessing, new to MIPS.)

Thanks everyone for your help so far!
