Treat common symbol in executable as definition

Common symbol in executable is a definition, which overrides definition
from shared objects. When linker sees a new definition from a shared
object, the new dynamic definition should be overridden by the previous
common symbol in executable.

together.

relocatable link, we can skip merging flags of other input sections.

Update PR ld/12365 test for GCC 6

PR ld/12365 test is to verify that linker catches the reference to
undefined symbol error caused by a GCC bug. Since the GCC bug has
been fixed in GCC 6, update the test to verify that there is no
reference to undefined symbol in executable
