[PATCH] AIX Build failure with default -std=gnu23.

libiberty/getopt.c file is defining _NO_PROTO which causes conflicting declarations for the functions in AIX header files like stdio.h & stdlib.h. These declarations are being considered as errors in C23 which wasn't the case with C17. Here is the error we get. /gcc_build/./prev-gcc/xgcc -B/g
