From 35c5deb1d43b245c19059d1532929ee087e44a84 Mon Sep 17 00:00:00 2001 From: Paul Murphy Date: Wed, 7 Jan 2026 13:48:53 -0600 Subject: 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.
