This breaks ELF programs in flat builds with
CONFIG_EXECFUNCS_SYSTEM_SYMTAB=y and CONFIG_HAVE_CXXINITIALIZE=y: crt0.c now
calls atexit(), but libs/libc/libc.csv does not export it, so every exec()
fails with ENOENT (reproduced on qemu-armv8a). Fix:
"atexit","stdlib.h","CONFIG_LIBC_MAX_EXITFUNS > 0","int","CODE void
(*)(void)"
