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.

     6 STABS hash table size change, backported from the binutils CVS tree.  Here's

     7 the CVS log comment for the original change:

    11 (_bfd_link_section_stabs): Use bfd_hash_table_init rather than

    12 bfd_hash_table_init_n(...,251) so that the size of the hash table can be

    13 controlled by the user.
