So, we have this shiny new patch which appears to correct paths for MIPS, but
when I try it with an n32 multilib, I get Very Strange failures.

The actual failing line, from gcc -v:

 ABI is incompatible with that of the selected emulation
[... and many more errors related to this

So, looking around, I see three crtbegin.o in the sysroot:
/usr/lib/mips-oe-linux/5.2.0/crtbegin.o
/usr/lib64/mips64-oemllib64-linux/5.2.0/crtbegin.o
/usr/lib32/mips64-oemllibn32-linux-gnun32/5.2.0/crtbegin.o

And presumably, I want the gnun32 library. But what it actually picked was:
/usr/lib64/../lib32/mips64-oe-linux/5.2.0/32/crtbegin.o

And that's the 32-bit (base library) crtbegin.o.

I am pretty sure that the gcc patch 0041 affects this but I honestly don't
entirely understand it.

Listen, get this.  Nobody with a good compiler needs to be justified.
