By the way, I've been meaning to ask:

$ /opt/android/x86_64/bin/clang --static -s hello.c && ls -l a.out
-rwxrwxr-x 1 landley landley 485880 Dec  2 22:10 a.out

$ ~/mcm/bin/x86_64-linux-musl-cc hello.c -s --static && ls -l a.out
-rwxrwxr-x 1 landley landley 17584 Dec  2 22:16 a.out

$ cat hello.c
#include <stdio.h>

int main(int argc, char *argv[])
{
  printf("hello world %d\n", 5);

  return 0;
}

Did that ever become... less bad? Yes, I'm forcing printf to do
something so gcc can't "optimize" it to puts, so it's a fair test. But
this seems to mostly be a "strip didn't" issue? A "grep -ai bionic" on
the stripped bionic binary (manually re-stripped to make sure) produced
stuff like:

(Although I'm pretty sure the strchr warning near the end there is
ubuntu 14.04's grep being buggy. Did I mention I break everything?)
