It looks like O_BINARY is already defined in system.h, so all it needs 
is the patches to open().

I backed off my shot gun fix and there are just two places that appear 
to be problem:

lto_elf_file_open () in lto-elf.c
lto_read_section_data() in lto.c

With O_BINARY on read/write remove failures from my simple test.
