branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
Since it was introduced in 5a6087d62e5c (toolchain: add powerpc SPE ABI
support), the CLASSIC vs. SPE choice for the ABI was never really a
choice: CPU without SPE could only use the CLASSIC ABI, while CPUs with
SPE could only use the SPE ABI.
Commit b4c824562bb1 (powerpc: add BR2_POWERPC_CPU_HAS_SPE to replace
adhoc deps/checks) added a blind option that CPUs with SPE would select
rather than duplicate the ad-hoc dependencies in both CLASSIC and SPE
ABI options. Since then, it was even more obvious that the ABI choice
was really not a choice, as the two options have mutually exclusive
conditions.
Drop the useless choice, and directly use the blind option as selected
by the specific CPUs.
We don't need legacy handling, because the situation fixes itself.
