Remove assert() if DT_RUNPATH and DT_RPATH flags are found in ld.so.

	* elf/dynamic-link.h (elf_get_dynamic_info): Remove assert()
	around DT_RUNPATH and DT_RPATH which prevents running a dynamic
	linker with an embedded RPATH flag, which is what a compiler
	modified to embed a non-default INTERP section would do.
