Make is_relocatable_executable only affect dynamic section syms

Make is_relocatable_executable only affect dynamic section syms

I believe the only elflink.c specialties for is_relocatable_executable
needed by tic6x are those directly related to dynamic section symbols.
I might be wrong, the code in record_dynamic_symbol and
record_link_assignment predated the tic6x port, but I think these were
symbian specific hacks.

The shlib-app-1* testsuite changes aren't needed for this patch.  I
started making them when trying to remove is_relocatable_executable
completely, but figure it is worth keeping the more permissive address
matching for some future generic linker change.  The static-app-1*
changes also adjust to the fact that an unneeded "c" no longer appears
in the dynamic symbol table.

bfd/
	* elflink.c (bfd_elf_link_record_dynamic_symbol): Don't do anything
	special for is_relocatable_executable.
	(bfd_elf_record_link_assignment): Likewise.
ld/
	* testsuite/ld-tic6x/shlib-app-1.rd: Make some address matching
	more permissive.
	* testsuite/ld-tic6x/shlib-app-1b.rd: Likewise.
	* testsuite/ld-tic6x/shlib-app-1r.rd: Likewise.
	* testsuite/ld-tic6x/shlib-app-1rb.rd: Likewise.
	* testsuite/ld-tic6x/static-app-1.rd: Likewise, and adjust expected
	dynamic symbol table.
	* testsuite/ld-tic6x/static-app-1b.rd: Likewise.
	* testsuite/ld-tic6x/static-app-1r.rd: Likewise.
	* testsuite/ld-tic6x/static-app-1rb.rd: Likewise.
