I greped in the Binutils git tree but I didn't see anything easy to backport to
fixes the issue. I tried to build a nios2 toolchain with gcc 5.2.3 and the
latest commit of the upcoming Binutils 2.26 release, and Qt GUI build fine.

I think we'll need to rebuild a new nios2 toolchain (with gcc 5.2.3 and binutils
2.26) to fix most of the build issues related to ld assertion fail or Assembler
messages (libcap-ng).

Also Qt GUI is not the only one affected by this issue (gtkmm3):

(Ok, likely not very used on nios2 ether)

Ok, let exclude Qt GUI on nios2 but other packages may have the same issue.
