From: Deepesh Varatharajan <Deepesh.Varatharajan@windriver.com>
For the powerpc64 machine with ppc64p9le tune, the supported ABI is elfv2
but the default elfv1 ABI is used and this causes link-time errors such as:
ABI version 1 is not compatible with ABI version 2 output
To resolve this, the powerpc64 machine with ppc64p9le tune is updated
with elfv2 ABI otherwise, default to elfv1 ABI. This change ensures
consistent ABI behavior across LLVM and Rust builds.
