>Description:

build.sh -m shark -O /... -T /usr/tools tools

creates a non-working tools objdump, same with -m eshark.

Same output from the created native eabi objdump.

This test was done with -current sources updated yesterday.

>How-To-Repeat:
This might be host / host-os-version dependend, others have said their 
amd64/current build of objdump is ok. Maybe the binutils build uses some
/bin/sh (or whatever) features not working on -6?

n/a
