[Buildroot] [PATCH] package/gcc: disable split-stack for non-thread builds for gcc powerpc spe

[Buildroot] [PATCH] package/gcc: disable split-stack for non-thread builds for gcc powerpc spe

[Romain Naour]

The toolchain for powerpc spe can use uClibc-ng without thread support.
So we need the same fix as commit [1].
