Ok, I see.

The only part I'm not sure about is the part that adds --enable-gdb to all configure
files.  For example we now have this in bfd's configure:

$ ./binutils/configure --help | grep gdb
  --enable-gdb[=ARG]     build gdb [ARG={yes,no}]

I understand that you want to catch whether the user enabled or disabled building GDB
with --enable-gdb or --disable-gdb, but the result is a bit weird.  Is there a way not
to include it in the --help?

Ideally, the top-level configure system would be able to tell which modules are enabled.
I don't know much about it, maybe there's a way.

In your patch, can

  : ${enable_largefile="no"}

become just

  enable_largefile="no"

?
