toplevel.mk: drop LD_LIBRARY_PATH overrides

Overriding LD_LIBRARY_PATH for host utilities frequently leads to problems
with host executables loading shared libraries from the staging_dir, leading
to crashes due to incompatible ABIs.

Since most host utilties either embed a proper rpath or are reworked to link
statically we do not need the workaround anymore.
