[Bug lto/42776] LTO doesn't work on non-ELF platforms.

There is a portability issue in is_elf_or_coff: fopen should be called with
"rb" instead of "r". Otherwise, fread fails when a COFF file has 26 sections,
because it is interpreted as a text, and 26 means "end of file".

Not tried. GCC and Binutils can be built with -flto under MSYS, and they seem
to work.
