linking: add and use LDFLAGS_common 

Add an LDFLAGS_common variable and use that for each stage
during linking within all the architectures. All the architectures
support gc-sections, and as such they should be linking in the
same way.

BUG=chrome-os-partner:44827
BRANCH=None
TEST=Built rambi and analyzed the relocatable ramstage.
