This indicates that another process is trying to use the same
temporary object file, and libtool could not work around it because
your compiler does not support '-c' and '-o' together.  If you
repeat this compilation, it may succeed, by chance, but you had better
avoid parallel builds (make -j) in this platform, or get a better
compiler."
