That rises an incompatibility problem when linking with GNU libc on kernel of
FreeBSD:

 - Glibc's ld.so works as shared object, but also as executable (needed
   for some extra features like ldd).
 - kernel of FreeBSD will refuse to exec() ld.so unless it was linked as an
   executable.

This problem is not necessarily specific to kfreebsd, but could also be with
other kernels (likewise, it's reasonable for a kernel to exec() only on
executables)

Either binutils or Glibc needs to be modified in order to support this
combination. I don't really have an opinion on which of them should be.
If you think Glibc is in fault, please add CC to
address@hidden on your response.
