 Nope, `--disable-gdb --enable-gdbserver' is typical for a cross-debug 
environment, where you want to configure and build cross-GDB with 
`--host=foo --target=bar' and `gdbserver' with `--host=bar'.  Sometimes 
your build environment may not even be capable to build native GDB with 
`--host=bar', or your target system to run it, and in any case building 
GDB takes a lot of processing time compared to `gdbserver'.  So it would 
be a waste of resources if we forced people to do that.

 I build `gdbserver' by itself routinely, although I only did the minimum 
to convert from the old layout, that is rather than calling `configure' 
from gdb/gdbserver/ I now call it from gdbserver/.  So far it has worked, 
although with the new arrangement it probably qualifies as a hack, and may 
stop working sometime.
