Alan Modra c5d37467b1 Undo dynamic symbol state after regular object sym type mismatch

We already handle the case of an object file first defining a symbol
that a later shared library also defines where the symbol types are
incompatible.  This patch handles the reverse, when a later object
file defines an incompatible symbol defined by an earlier shared
library.

bfd/
	* elflink.c (_bfd_elf_merge_symbol): Undo dynamic linking
	state when a regular object file defines a symbol with
	incompatible type to that defined by an earlier shared lib.

	* testsuite/ld-elf/indirect6a.c: Likewise.
	* testsuite/ld-elf/indirect.exp (check_dynamic_syms): New proc.
	Run new tests and check dynsyms.
