i also had this problem when trying to cross-link from linux to target
`i386-msdos-go32'.  after running ld through the debugger, it turns
out that the `-o' option was being interpreted as `-oformat' option,
so it is trying to create an object file of type `foo.o'.

it turns out that `getopt_long_only ()' was returning incorrect
information when called from `parse_args ()' in ld/lexsup.c, but when
i tried to trace into `getopt_long_only ()' the debugger barfed
because of the no symbols were found for getopt[1].c, even tho they
had been compiled `-g'.  i didn't have time to investigate the failure
further, but this total hack patch produces a working cross-ld:
