[Ada] fix warning when printing empty array

This patch should fix the following regression:

     (gdb) print my_table
    -$1 = ()
    -(gdb) PASS: gdb.ada/null_array.exp: print my_table
    +$1 = (warning: unable to get bounds of array, assuming null array
    +)
    +(gdb) FAIL: gdb.ada/null_array.exp: print my_table

The problem was introduced by a change in val_print_array_elements
which removed a check for the case where the array's high bound
is smaller than the array's low bound (empty array).

This change restores the check and forces the len to zero in that case.
Looking at the patch that caused the regression, I suspect that we may
have other parts that might have been broken (non-zero array low bound?).

        empty arrays.

fix typo in _FILE_OFFSET_BITS comment

This fixes a typo that MichaelS noticed in a patch I submitted and
forgot to fix.

gdb/ChangeLog:

* (_FILE_OFFSET_BITS): Fix typo in comment.

Fix build failures with python support on sparc-solaris

There were two types of errors, mostly compiler warnings:

  1. _FILE_OFFSET_BITS being redefined in pyconfig.h;
     This is a problem we're familiar with, having seen similar
     issues on GNU/Linux systems. I used a similar solution.

  2. GCC 4.5 complains that calls to PyEval_InitThreads and
     PyEval_ReleaseLock have no effect.  This is because our Python
     is built without thread support, leading us to use the dummy
     #define in python-internal.h which just gets replaced by `0'.
     Since this function returns void (checked versions 2.4 and 2.7),
     I simply removed the 0.

gdb/ChangeLog:

        python/python-internal.h (_FILE_OFFSET_BITS): Undefine.
        (PyEval_InitThreads): Remove duplicate. Define as nothing.
        (PyEval_ReleaseLock): Define as nothing.

gdb/ChangeLog:

        * dwarf2read.c (psymtab_include_file_name): Replace call to strcmp

avoid assignment inside if condition (dictionary.c)

This change gets rid of an ARI warning which was recently introduced

        * dictionary.c (dict_hash): Move assignment out of if condition.
