The MIPS parts look OK to me FWIW.  In the doc part:

+Use uClibc instead of the GNU C library.  This is the default on
+@samp{*-*-linux-*uclibc*} targets.  GCC currently only supports uClibc
+on ARM and MIPS targets.

it might be better to emphasise that the MIPS support is restricted
to 32-bit targets.  It doesn't work on mips64-linux-gnu.
