microblaze: fix variable name collision with syscall macros
If a function passes in a variable named "ret", the code will miscompile when it declares a local ret variable. In some cases, it's even a build failure like so: ../sysdeps/unix/sysv/linux/spawni.c: In function '__spawni_child': ../sysdeps/unix/sysv/linux/spawni.c:289:5: error: address of register variable 'ret' requested while (write_not_cancel (p, &ret, sizeof ret) < 0)
