PowerPC64: stub uses new strategy

Needed: expert on TOC for big-endian. glibc, musl, gcc disagree on layout (is the .func first?) and usage for .e_entry. modified: p_lx_elf.cpp modified: stub/src/amd64-linux.elf-main.c modified: stub/src/amd64-linux.elf-fold.S modified: stub/src/arch/powerpc/64le/ppc_regs.h modified: stub/src/i386-linux.elf-main.c modified: stub/src/powerpc-linux.elf-entry.S modified: stub/src/powerpc-linux.elf-fold.S modified: stub/src/powerpc64le-darwin.dylib-entry.S modified: stub/src/powerpc64le-darwin.macho-entry.S modified: stub/src/powerpc64le-linux.elf-entry.S modified: stub/src/powerpc64le-linux.elf-fold.S modified: stub/Makefile also .h, .bin.dump, .map
