G4 does not have SPE, so we make that explicit in the tune files and
since we emulate G4 when building Qemu, we ensure it for qemuppc as
well.
GCC config for powerpc-linux is made to include SPE by default which is
equivalent if the tripet was powerpc-linux*spe, this forces gcc to
configure assembler to enable -mspe by default, when we do that then the
kernel fails to compile with binutils 2.26, since newer assembler is
smart to detect the tlbia instructions are not compatible with SPE and
hence the kernel build breaks rightly. We configure the kernel for G4 as
well where it enables tlbia instrucitons rightly so because it thinks
its being configured for power4. So we keep the options but do not force
-mspe down to assembler as default.

The gcc 5.3 does not build on NIOS2 due to a missing MUSL_DYNAMIC_LINKER
definition in it's config file. Add the definition to fix the build issue.
The output produced during the failing build is as follows:
