Hi!

Could you please correct a tiny bug in the MIPS ELF BFD ?

$ file c3640-is-mz.120-28a.bin
c3640-is-mz.120-28a.bin: ELF 32-bit MSB executable, version 1 (SYSV), 
statically linked, stripped

CISCO IOS for 3600 is a conventional MIPS-BE ELF.
For obscurity reason they've deleted a ELF *section names*.
