Hi!
Clearly I can't count, so we would consider as SECTION_BSS even sections
like .lbssfoo or .gnu.linkonce.lbbar, even when linker only considers as
special .lbss or .lbss.baz or .gnu.linkonce.lb.qux.
Fixed thusly, bootstrapped/regtested on x86_64-linux and i686-linux,
committed to trunk as obvious.
