gdb: fix building with system readline
Building gdb with --enable-targets=all and --with-system-readline hits a
failure in a few targets all related to the inclusion of some opcodes
headers. The usage of the bundled readline results in an -I to the top
srcdir, but if that isn't used, then there is no such -I path. A few gdb
targets use this implicitly to include opcodes/ source header files. So
make sure there is always an explicit -I path to the opcodes/ directory.

sim: always enable support for the --endian option
The gdb code always passes down -E <little|big> to the sim core when using
the sim target. But the sim core only recognizes this option when the sim
supports big endian systems. So for little endian simulators, any attempt
to use the sim target fails with:
(gdb) target sim
gdbsim: invalid option -- 'E'
unable to create simulator instance
Since always respecting the option doesn't cause any problems, do just
that. If someone tries to use an invalid endian, they'll get an error
anyways.

[dwarf] Anonymous nested function causes SEGV during psymbol read
According to the DWARF3 standard, a function always has a name attribute
(Section 3.3 - Subroutine and Entry Point Entries). The only exception
is when a DW_AT_abstract_origin attribute is provided, in which case
the name may be inherited from the referenced DIE.
The problem occured because our compiler generated a subprogram DIE
for a nested function where the name attribute was missing (and no
abstract-origin either). Our code in add_partial_symbol is not
prepared to deal with the situation, and happily just tries to compute
the length of the (NULL) function name.
This normally cannot happen, because there is already a guard in
scan_partial_symbols, where we (silently!) ignore anonymous dies,
including anonymous subprograms. Unfortunately, there is a flaw that
affects Ada and other languages that allow nested subprograms. For
nested subprograms, we do not go through scan_partial_symbols and
thus we are missing the name check.
This patch adds the name check in the nested subprogram case. It also
adds a complaint which is emitted during the psymtab->symtab conversion
phase.
gdb/ChangeLog:
* dwarf2read.c (add_partial_subprogram): Make sure the subprogram
DIE has a name before creating the associated partial symbol.
(read_func_scope): Emit a complaint if the subprogram does not
have a name or when we can't extract the subprogram PC bounds.
gdb/testsuite/ChangeLog:
* gdb.dwarf2/dw2-anonymous-func.S: New file.
* gdb.dwarf2/dw2-anonymous-func.exp: New testcase.
Tested on x86_64-linux, no regression. Note that the testcase also
verifies that the psymtab->symtab conversion does not crash (this is
the purpose of the "list file1.txt:1" test.

Avoid switch to invalid ptid during Ada task switch.
This is to prevent an internal error during an Ada task switch. A task
switch is simply a thread switch under the hood. What we do is collect
the info from the Ada Task Control Block, deduce the associated thread
ptid, and then switch to that thread. If the thread ptid computation
routine has not been implemented for the target, of if there is a bug,
then we end up computing a bogus ptid which GDB does not know about,
which eventually leads to an assertion failure:
(gdb) task 1
[New Thread 5715]
/[...]/gdb/thread.c:595: internal-error: is_thread_state:
Assertion `tp' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
When this happens, it's just nicer for the user to print an error
message, and cancel the task switch. After this patch is applied,
this is what we get:
(gdb) task 1
[New Thread 10250]
Unable to compute thread ID for task 1.
Cannot switch to this task.
