Building newlib-2.1.0 for m68k fails

On Cygwin I'm building gcc-4.91 along with newlib-2.1.0 for a mingw host and
an m68k ELF target. Building newlib failed when trying to compile io-read.c
because the return type of read is a ssize_t but the prototype uses
_READ_WRITE_RETURN_TYPE which in my configuration was defined to int. The
attached patch fixed the problem.
