Recompiling trunk mipsel natively eventually failed:

/usr/bin/diff ppc3 ppcmipsel
Binary files ppc3 and ppcmipsel differ
make[2]: *** [cycle] Error 2

I think what I need to do is revert to the last version I've seen a full 
build working on, I've got the sources but not the svn metadata so I 
can't for the moment say what revision this is.

Is there a rough way of querying svn to determine what revisions were 
committed on a particular date?

For the record, Qemu describes its mipsel emulation as

system type             : MIPS Malta
processor               : 0
cpu model               : MIPS 24Kc V0.0  FPU V0.0
BogoMIPS                : 98.04
wait instruction        : yes
microsecond timers      : yes
tlb_entries             : 16
extra interrupt vector  : yes
hardware watchpoint     : yes, count: 1, address/irw mask: [0x0ff8]
ASEs implemented        :
shadow register sets    : 1
core                    : 0
VCED exceptions         : not available
VCEI exceptions         : not available
