Just a guess, but perhaps this is not a linking error at all. This looks to me
like ld calling write() and the call itself returning ENOSYS. Is there
something unusual about the filesystem you’re writing dummy.so to? If the write
fails but the file size also increases, I wonder if what you’re seeing is some
sort of I/O error. Anything exciting in dmesg and friends?
