Subject: ldd not working on ET_EXEC executables

Hello,

I am running musl on a ARM platform, and ldd won't work on a executable with the ET_EXEC type.

running GNU ld 2.25.1, gcc 6.2.0, and musl 1.1.15-git-71-g54991729

  $ gcc -fPIE -pie test.c -o test-pie
  $ ldd test-pie
<no error>
  $ gcc -fno-PIE -no-pie test.c -o test-nopie
  $ ldd test-nopie
ldd: test-nopie: Not a valid dynamic program
  $ elfedit --output-type DYN test-nopie
  $ ldd test-nopie
<no error>

Any idea why ldd says executables with the ET_EXEC type aren't valid?
