urgent, I'd say go ahead and commit your patch.
Besides, there are two typos:

My patch still applies cleanly to current HEAD, has this migration happened already? If not, what's the current ETA? I'll have almost no spare time after this week, I'd like to sort this out before/during the weekend if possible. Thanks! -- Robert Millan

Ok then. I'd appreciate if you can send me a reminder via private mail when you've finished. Best regards -- Robert Millan

(few days / weeks / months) I'm in the middle of moving shlib support (another day), need to rebase crtstuff and libgcc1, and finish libgcc2. I hope to be ready within two or three weeks.

Robert Millan
2011-07-22 Robert Millan
Support for GNU/kFreeBSD systems running on MIPS.
* config.gcc: Detect mips*-*-kfreebsd*-gnu.
* config.host: Likewise.
* config/mips/kfreebsd-gnu.h: New file.
* config/mips/kfreebsd-gnu64.h: New file.
* config/mips/gnu-user.h: Restrict `-march=native' support to GNU/Linux.
