The alternative would probably be to force compilation in normal mips
mode for all of glib (as is done for armv4 and armv5). While that
would retain the valgrind support, valgrind support itself shouldn't
be needed on the target device, and we rather keep the mips16e mode.

I think this is a list of patches. Not this alone. You need MIPS_INSTRUCTION_SET
patch to begin with. I am not sure its safe and desired to bring mips16 feature after
the release.
