Add PPC64LE (POWER9+, little-endian) as a recognized platform for interpreter-only builds. No dynarec code is included yet. Platform support: - Build system: CMakeLists.txt cross-compiler setup, CPACK, CONFIG_64BIT - CI: GitHub Actions matrix with qemu-ppc64le-static testing - Host CPU feature detection (CRYPTO, DARN, ISA 3.1, MMA) - Signal handling for PPC64LE (xSPSave/old_savedsp, context registers) - O_LARGEFILE conversion (PPC64LE uses 0200000) - Static build: -fno-stack-protector (glibc uses TLS-based canary via r13) - __stack_chk_guard guard for PPC64LE static builds - Wrapper generator PPC64LE support

Summary
Add PPC64LE (POWER8+ little-endian) platform support for box64 in interpreter-only mode. This is the first of a series of incremental PRs to bring PPC64LE support to box64, split from the original #3563 based on review feedback.
This PR contains only platform support infrastructure — no dynarec code.

This PR enables box64 to build and run on PPC64LE in interpreter-only mode. The dynarec infrastructure will follow in a separate PR.
