[PATCH] busybox: fix menuconfig on newer hosts

[PATCH] busybox: fix menuconfig on newer hosts

[Dan McGregor]

From: Dan McGregor <dan.mcgregor@usask.ca>

The lxdialog.sh script compiles a short program as a link test. That
test program relied on an implicit return type of the main function,
but gcc >= 14 now warns on that by default. This caused the test
to fail and prevented menuconfig from starting.

Use a full function declaration to fix this, allowing menuconfig to
once again run on a newer host.

+New gcc warns by default if a function is declared without a return
