This patch resolves the following build error which occurs with gcc 14.1.0:
../../.././libgloss/microblaze/linux-outbyte.c: In function 'outbyte':
../../.././libgloss/microblaze/linux-outbyte.c:3:9: error: implicit declaration of function '_write' [-Wimplicit-function-declaration]
    3 |         _write(1, &c, 1);
