PowerPC64 stub: on syscall, real Linux trashes r13 and below
(except r1, r2, and input args!) So, r12 .e_entry for musl must copy from a saved register. [qemu-ppc64 doesn't trash registers!] modified: ../.github/travis_testsuite_1.sh modified: p_lx_elf.cpp modified: stub/src/amd64-linux.elf-main.c modified: stub/src/powerpc64le-linux.elf-fold.S also .h .fold.map
