ld: Add an LTO test for common symbol override

Linker checks if a symbol in an archive member is a real definition, not
common, before including the archive member in the link output so that
only a real definition in archive will override the common symbol in
object file.  Add an LTO test to verify that a real definition in archive
overrides the common symbol in object file.

	* testsuite/ld-plugin/common-1.c: New file.
	* testsuite/ld-plugin/definition-1.c: Likewise.
	* testsuite/ld-plugin/lto.exp: Run common tests.
