Separate debuginfo and executable in two different files.

# generate-debuginfo
# ==================
#
# This is a tiny example that shows how to have a debug-stripped
# executable and a separate debug information file that can be
# loaded by GDB. This is useful since you may not want to ship
# the executable with debuginfo, but you may optionally provide
# the info seperately.

# Build executable
$ cat > main.c << EOF
#include <stdio.h>
int main() {
    printf("Hello, World!\n");
    return 0;
}
EOF
$ gcc -g -o main main.c

# Separate debug symbols from the executable
$ objcopy --only-keep-debug main main.debug
$ strip --strip-debug maon
$ ls
main  main.c  main.debug

# Debug with GDB
$ gdb --exec=main --symbols=main.debug
