I should have added: An option may be to link twice: Once with debug info
included, and once with it stripped. Personally I trust the linker creating
the various headers, including the section ones, more than strip's (or
objcopy's). Yet then I can only repeat my observation that linking PE+ from
ELF inputs looks to be significantly slower than linking ELF -> ELF.
