Hmm, actually this is only place where SHN_X86_64_LCOMMON is introduced.
If I set the section as it is constructed from tc-i386.c I still get
GLOBAL visibility out of resulting file and I am not quite sure where
the SHN_X86_64_LCOMMON should be introduced (I originally attempted to
set it directly in gas when creating the symbol but that thing don't
seems to be used).
Perhaps I am constructing the .lbss section incorrectly but I am not
quite sure what is proper way here...
