Use file, chatr, ldd and readelf commands to check file type and ELF
information.  Compare with native application.

GNU ld doesn't create "static" executables (known problem).  It
can only create dynamic executables.  Typically, problems in launching
dynamic executables are debugged by running the dynamic linker under
gdb.  This is hard here because the dynamic linker is proprietary.

3 is probably a binutils bug.  I haven't tried a native build
using GNU ld for some time.  It used to be good enough to do what
you want.
