As Gustavo said yesterday on IRC about Qemu-kernel-target version matching
"sometimes there's a star alignment where everything works, but that's not
always the case", here is the same about binutils-gcc-target.

The new nios2 toolchain doesn't work here due to binutils-gcc version mismatch
(binutils 2.26.1 and gcc 5.4). I also tried with several build options (O1 and
02) but it still fail with the same error.

I've build some nios2 toolchains and it appear that gcc5 require binutils <=
2.25 on this platform.
If gcc6 is used with binutils 2.26.1, alsa-lib build fine.

For now, I haven't investigated on the gcc history to find an upstream patch to
backport but it can be time consuming...

So, ether we rebuild the nios2 toolchain with binutils 2.25.1 or we bump the gcc
version. But we have to rebuild this toolchain anyway.

I would suggest to fallback to binutils 2.25.1 in order to avoid gcc6 issue (we
already have our bleeding edge toolchain for that ;-) ).

Code Sourcery Binutils issue (fixed in our internal toolchain):
BFD (Sourcery CodeBench Lite 2016.05-10) 2.25.51 assertion fail

Add an autobuilder exception for this toolchain ?

/tmp/ccKF8wFF.s: Assembler messages:
/tmp/ccKF8wFF.s:5644: Error: r31 cannot be used with jmp; use ret instead

Same toolchain issue than for alsa-lib.

Not related to nios2.
