I've built a binutils-2.15 with a just plain "./configure --target=mips-ecoff"

This makes a object files with JMPADDR as required by VxWorks loader!



$ /mips/binutils-2.15/binutils/objdump -i
BFD header file version 2.15
ecoff-bigmips
(header big endian, data big endian)
 mips
ecoff-littlemips
(header little endian, data little endian)
 mips
...
$ /mips//binutils-2.15/binutils/objdump -x /mips/app/hellovx/test.o
