[PATCH] fix make menuconfig when using gcc 14

[Nop]

Hello,
I sent that more or less same patch months ago, which was included in
buildroot.
The difference with my patch is that I also removed the 2>/dev/null
redirection so that it does not hide the issue and I added a return zero
because AFAIK the C programming does not allow the main to omit the return,
this is actually defined in C++ and GCC allows it as a non-standard
extension. So to avoid any future warning if the diagnostic level is raised
again, I just prefer writing everything explicitely once and for all.
