[patch][rfa]: objdump.c -- SKIP_ZEROES, SKIP_ZEROES_AT_END

[Dave Brolley]

Hi,

Many new targets have long instructions words and many new isa's have 
valid insns which are all zeroes. Objdump uses two macros, SKIP_ZEROES 
and SKIP_ZEROES_AT END, to decide when to skip over sequences of 
zero-bytes instead of disassembling them. The attached patch allows 
individual ports to set these macros to suitable values via OBJDUMP_DEFS 
in configure.in.

Ok to commit?

Dave
