 I did some investigation actually as I noticed this new failure a few 
weeks ago, and I have a change in progress I haven't yet had time to 
complete.  I came to the conclusion in the MIPS case empty `.reginfo', 
`.MIPS.options' and `.MIPS.abiflags' sections should simply be discarded 
(i.e. preferebly not created in output in the first place and ignored if 
seen) as they are meaningless anyway.  Otherwise we end up with broken ELF 
files we cannot handle anymore, not even `objcopy' them to fix that.

 So obviously I'll now have to revert this change along the proper fix.
