With the current binutils, symbols from libheimtlm.so are loaded because
it is referenced by DT_NEEDED. This feature is not implemented in
mclinker (https://code.google.com/p/mclinker/issues/detail?id=104).
I encountered the same issue when linking with a recent devel/binutils
invoked via clang. This was the only use of DT_NEEDED in the tree so
removing it simplifies toolchain requirements.
