Require --no-dynamic-linker with -static -E/--dynamic-list

Browse Source 
When -static -E/--dynamic-list are passed to linker, linker may create
executable with dynamic sections which aren't supported by run-time.
We require --no-dynamic-linker together with -static -E/--dynamic-list
before adding dynamic symbol table to static executable.

	--no-dynamic-linker with -E/--dynamic-list when creating
	dynamic sections.
