excessive stab information

[Andy Chittenden]

I've now sorted out our #includes so that no header file defines a type
within a #ifdef. This did save around 3% on the size of an elf so thanks
for that suggestion. However, we still have massive stabs. Further
analysis of the output of objdump --stabs led me to develop this patch
to bfd/stabs.c which removes a further 2%: is it ok to apply?
