all: switch linux-ppc64 target to ELFv2 ABI
Go is only capable of producing internally linked, static binaries
on linux-ppc64. As such, binaries should run in either ELFv1 or
ELFv2 ppc64 userspaces today.
This opens the door to enabling cgo and external linking which
will require ELFv2 support and userspace, eventually.
Fixes #76244
