Make linker assigned symbol dynamic only for shared object 

Linker assigned symbols should be made dynamic by default only when
creating shared object or relocatable executable.

bfd/

	* elflink.c (bfd_elf_record_link_assignment): Check for shared
	library, instead of PIC, and don't check PDE when making linker
	assigned symbol dynamic.

ld/

	* testsuite/ld-frv/fdpic-pie-6.d: Updated.
	* testsuite/ld-mips-elf/pie-n32.d: Likewise.
	* testsuite/ld-mips-elf/pie-n64.d: Likewise.
	* testsuite/ld-mips-elf/pie-o32.d: Likewise.
