Linkers prepend a _ to symbols; not all show it.  Thus, _errno is  
likely supposed to be errno, which is a global variable from libc  
(specifically, errno.h); however, in a threaded libc, errno is  
actually preprocessor macro that looks like this

  #define errno  (*__errno_location ())

This sounds like your linker is trying to find an actual "errno"  
symbol because the C compiler didn't see the proper preprocessor  
definition of errno at .c -> .o time.

Check the includes and see if errno.h is being included.

A description of the platform and toolchain would be invaluable.
