Hmm, maybe Python is not relevant here, because we have,
in gdb/python/py-gdb-readline.c:

/* Initialize Python readline support. */

void
gdbpy_initialize_gdb_readline (void)
{
/* Python's readline module conflicts with GDB's use of readline
since readline is not reentrant. Ideally, a reentrant wrapper to
GDB's readline should be implemented to replace Python's readline
and prevent conflicts. For now, this file implements a
sys.meta_path finder that simply fails to import the readline
module. */

That still leaves open the question about non-GNU/Linux OSs, though.
