I'm trying to track this down and fix it, but mine didn't even get that far, 
it died with:

  CC      arch/um/kernel/ptrace.o

There is no expression #4 in that.  It has three expressions (-e arguments) 
and a filename...

I know sed.  I wrote and maintain the current busybox sed implementation.  I 
just don't know what the build's doing.

Could you send me your .config?

I'm confused: what?
