[PATCH] libgloss: fix read and write prototype

Use _READ_WRITE_RETURN_TYPE for read/write in libgloss/{read,write}.c to
avoid mismatching types.

Hello,

building with gcc14-rc for m68k fails with (see my mail earlier this week):

 src/newlib/libgloss/m68k/../read.c:24:1: error: conflicting types for 'read'; have 'int(int,  void *, size_t)' {aka 'int(int,  void *, long unsigned int)'}

This simple fix makes use of _READ_WRITE_RETURN_TYPE macro to avoid mismatching types.

Marc
