Subject: dxe.ld doesn't handle linkonce.b sections
To: djgpp <djgpp AT delorie DOT com>

Our current dxe.ld doesn't handle .gnu.linkonce.b.* sections.
Objects built with -ffunction-sections -fdata-sections fail,
because the current dxe.ld doesn't handle .bss.* either.
Never needed/used it, but lto sections possibly need discarding
as in djgpp.ld.

Is the following patch correct?  Haven't actually run-tested it
yet, but posting it for review for now:

 }


The .bss.*sections are handled diferently in djgpp.ld, though:
Should we do the same in dxe.ld?
