Fully agreed to remove SPARC from the list of supported architectures
for webkit and script. However, I believe it would still be good to add
the BR2_TOOLCHAIN_HAS_SYNC_4 dependency as well.

Regarding the architectures that build but don't work at runtime, I
guess all we can do is leave things are they are, and change them
when/if someone complains/reports an issue. We are indeed not going to
test Webkit/Script on every possible funky architecture.

Best regards,

Thomas
