Martin Jansa 33c96b7ed8 nodejs: use PIE for host binaries 
* mksnapshot is built as host binary, but then gets executed under
  qemu-arm, because for 32bit target we need to run 32bit mksnapshot
  even when building on x86-64 host

* unfortunately since upgrade to qemu-8 in:
  https://git.openembedded.org/openembedded-core/commit/?id=fe8125565af07b73f9b29db2188ecb6e884bcc70

  the mksnapshot fails to execute with:
  LD_LIBRARY_PATH=/OE/build/oe-core/tmp-glibc/work/cortexa8t2hf-neon-oe-linux-gnueabi/nodejs/18.16.0-r0/node-v18.16.0/out/Release/lib.host:/OE/build/oe-core/tmp-glibc/work/cortexa8t2hf-neon-oe-linux-gnueabi/nodejs/18.16.0-r0/node-v18.16.0/out/Release/lib.target:$LD_LIBRARY_PATH; export LD_LIBRARY_PATH; cd ../tools/v8_gypfiles; mkdir -p /OE/build/oe-core/tmp-glibc/work/cortexa8t2hf-neon-oe-linux-gnueabi/nodejs/18.16.0-r0/node-v18.16.0/out/Release/obj.target/v8_snapshot/geni; "/OE/build/oe-core/tmp-glibc/work/cortexa8t2hf-neon-oe-linux-gnueabi/nodejs/18.16.0-r0/node-v18.16.0/out/Release/v8-qemu-wrapper.sh" "/OE/build/oe-core/tmp-glibc/work/cortexa8t2hf-neon-oe-linux-gnueabi/nodejs/18.16.0-r0/node-v18.16.0/out/Release/mksnapshot" --turbo_instruction_scheduling "--target_os=linux" "--target_arch=arm" --startup_src "/OE/build/oe-core/tmp-glibc/work/cortexa8t2hf-neon-oe-linux-gnueabi/nodejs/18.16.0-r0/node-v18.16.0/out/Release/obj.target/v8_snapshot/geni/snapshot.cc" --embedded_variant Default --embedded_src "/OE/build/oe-core/tmp-glibc/work/cortexa8t2hf-neon-oe-linux-gnueabi/nodejs/18.16.0-r0/node-v18.16.0/out/Release/obj.target/v8_snapshot/geni/embedded.S" --no-native-code-counters

  It was failing only in some of my builds first, in the end
  I was able to narrow the difference between the build where
  it fails and where it doesn't fail to
  require conf/distro/include/security_flags.inc
  then
  GCCPIE = "--enable-default-pie"
  and lastly this PIE enabled just for nodejs to work around
  this issue without downgrading qemu-native.

* using -strace with qemu doesn't help much, just confirms that
  the OOM error message is really caused by failed mmap2:

  --- SIGPROF {si_signo=SIGPROF, si_code=SI_TKILL, si_pid=2908258, si_uid=1026} ---
  clock_gettime64(CLOCK_MONOTONIC,0x407ef640) = 0 ({tv_sec=20187,tv_nsec=678404286})
  rt_sigreturn(0x407efb70) = -1 errno=513 (Successful exit from sigreturn)
  write(3,0x141e538,28) = 28
  write(3,0x141e538,28) = 28
  write(3,0x141e538,32) = 32
  mmap2(0x0097a000,33554432,PROT_NONE,MAP_PRIVATE|MAP_ANONYMOUS|MAP_NORESERVE,-1,0) = -1 errno=12 (Cannot allocate memory)
  mmap2(0x0097a000,33554432,PROT_NONE,MAP_PRIVATE|MAP_ANONYMOUS|MAP_NORESERVE,-1,0) = -1 errno=12 (Cannot allocate memory)

* diffoscope on this 1.7G binary didn't really help as it got killed by OOMK after a while
