debug/cross-gdb: check host dependencies

Cross-gdb depends on expat and python. If either is missing, cross-gdb will
build successfully, but lacking some features.

Especially, if expat is missing, cross-gdb will be unable to parse the target
description, which may lead to runtime malfunctions and the following GDB
warning:
"Can not parse XML target description; XML support was disabled at compile time"

Hence, expat should be considered mandatory.

On the other hand, the features missing without python are not critical, so
python should not be considered mandatory.

This patch does the following:
- At configure time, warn the user if either expat or python is missing.
- In menuconfig, disable the static build options regarding cross-gdb if no
static version of expat is available, and disable cross-gdb if expat is
missing.

    22 If you want to enhance crosstool-NG, there's a to-do list in the TODO file.

    24 Patches should come with the appropriate SoB line. A SoB line is typically

    25 something like:

    28 The SoB line is clearly described in Documentation/SubmittingPatches , section

    29 12, of your favourite Linux kernel source tree.

    32 For larger or more frequent contributions, mercurial should be used.

    33 There is a nice, complete and step-by-step tutorial in section 'C'.
