There's some strange bug in glibc that triggers if you combine the
--gc-sections linker flag with static linking. If this happens, then
the "stdout" variable (used by printf() and such) will only work if stdout
is _not_ redirected. I.E "./busybox" prints stuff, but "./busybox | cat"
does not produce any output. (But even when redirected, "write(1,"blah",4);"
continues to work just fine.)
This is clearly a glibc bug, but to avoid triggering it I've moved the
--gc-sections flag so it only gets added when we're not statically linking.
If somebody would like to go poke Ulrich Drepper, you can trivially reproduce
this with a "hello world" program, ala:
gcc -static -Wl,--gc-sections hello.c && (./a.out | cat)
