Enable OpenHPC builds on ppc64le (IBM POWER) across the affected spec files. ppc64le-specific changes are gated by %ifarch ppc64le so the existing x86_64 and aarch64 builds are unaffected. The POWER9 baseline (-mcpu=power9) matches the EL9+ ppc64le distro minimum (redhat-rpm-config %__cflags_arch_ppc64le) and is forward- compatible with POWER10/POWER11. Verified by building every touched package on both x86_64 and ppc64le; no regression on the existing architectures.

Upstream-candidate PR-1 — ppc64le port (review preview)
This is the isolated ppc64le (IBM POWER) architecture support intended for upstream OpenHPC 4.x, presented as a single clean commit for review. The base branch
ppc64le-review-baseis the fork's merged-upstream state with the port reverted, so this diff shows ONLY the ppc64le changes — none of the upstream re-merge, validation harness, or openEuler distro work.What it does
14 spec/build files, all ppc64le changes gated by
%ifarch ppc64le(or ccache/openEuler conditionals) so x86_64 / aarch64 are unaffected: POWER9 compiler baseline, OpenBLASTARGET=POWER9, FFTW--enable-vsx, Boostarchitecture=power, likwidGCCPOWER+ perfevent patch, PDToolkitibm64linux, numpy VSX3 fix (fail-loud guarded), and meta-package arch closure.Verification (on real hardware, in podman containers)
Review base is synthetic (for diff isolation); not a real merge target.
