Enable target sparc-softmmu

[mikel-fernandez]

Some changes added to enable the generation of the sparc-softmmu target.

Changes now enable: ./configure --target-list="sparc-softmmu" --disable-kvm --audio-card-list="" --disable-vnc-jpeg --disable-vnc-png --disable-strip make

Tests: I checked that the x86_64-softmmu target is still generated: ./configure --target-list="x86_64-softmmu" --disable-kvm --audio-card-list="" --disable-vnc-jpeg --disable-vnc-png --disable-strip make
