need to mark the igen tool as a recursive dep. Each port depends on
the tool if it actually uses it, and ppc doesn't use it at all.

Pass internal gdb flags to --configuration invocations
The test suite uses the --configuration flag to feature-test gdb.
However, when I added this, I neglected to pass the internal gdbflags
to this, causing an error, which then caused failures in the test
suite (which would not be seen if you'd ever run "make install").
This patch fixes the bug. Tested by removing my install tree first,

Use unsupported in 'require'

The latter doesn't really seem to be correct according to the DejaGNU

Declares a test was not run. `untested' writes in the log file a
message beginning with _UNTESTED_, appending the `message' argument.
For example, you might use this in a dummy test whose only role is to
record that a test does not yet exist for some feature.
The example there, and some text elsewhere, is what makes me think
this isn't a great fit. On the other hand, 'unsupported' says:
Declares that a test case depends on some facility that does not exist
in the testing environment.

A user pointed out that "ptype/o" of a certain Ada type -- while in C
mode -- caused gdb to crash.
The bug here is that dynamic types can't really be printed this way.
This patch avoids the bug by disabling the "/o" feature in this case.
Note that using "ptype/o" in this way makes sense for the time being,
because the Ada code doesn't support the "/o" feature (yet); and in
any case gdb should not crash.

ARM: Fix ld bloat introduced between binutils-2.38 and 2.39
Since commit
9833b7757d24, "PR28824, relro security issues",
ELF_MAXPAGESIZE matters much more, with regards to layout of
the linked file. That commit fixed an actual bug, but also
exposes a problem for targets were that value is too high.
For example, for ARM(32, a.k.a. "Aarch32") specifically
bfd_arch_arm, it's set to 64 KiB, making all Linux(/GNU)
targets pay an extra amount of up to 60 KiB of bloat in
DSO:s and executables. This matters when there are many
such files, and where storage is expensive.
It's *mostly* bloat when using a Linux kernel, as ARM(32) is
a good example of an target where ELF_MAXPAGESIZE is set to
an extreme value for an obscure corner-case. The ARM
(32-bit) kernel has 4 KiB pages, has had that value forever,
and can't be configured to any other value. The use-case is
IIUC "Aarch32" emulation on an "Aarch64" (arm64) kernel, but
not just that, but a setup where the Linux page-size is
configured to something other than the *default* 4 KiB. Not
sure there actually any such systems in use, again with
both Aarch32 compatibility support and a non-4KiB pagesize,
with all the warnings in the kernel config and requiring the
"EXPERT" level set on.
So, let's do like x86-64 in
a2267dbfc9e1 "x86-64: Use only
one default max-page-size" and set ELF_MAXPAGESIZE to 4096.
bfd:
* elf32-arm.c (ELF_MAXPAGESIZE): Always set to 0x1000.

ld/testsuite: Adjust for ELF_MAXPAGESIZE 0x1000
Many tests reflect a setting of ELF_MAXPAGESIZE to 64 KiB.
With ELF_MAXPAGESIZE changed to 4 KiB, layout is sometimes
different and symbols end up in other places. Avoid churn
and regexpification of old test patterns by passing the
max-page-size setting active at the time.

Pass -z max-page-size=0x10000 explicitly to test that rely on
that value in output-matching patterns.

libctf: ctf-link outdated input check faulty
This check has a pair of faults which, combined, can lead to memory
corruption. Firstly, it assumes that the values of the ctf_link_inputs
hash are ctf_dict_t's: they are not, they are ctf_link_input_t's, a much
shorter structure. So the flags check which is the core of this is
faulty (but happens, by chance, to give the right output on most
architectures, since usually we happen to get a 0 here, so the test that
checks this usually passes). Worse, the warning that is emitted when
the test fails is added to the wrong dict -- it's added to the input
dict, whose warning list is never consumed, rendering the whole check
useless. But the dict it adds to is still the wrong type, so we end up
overwriting something deep in memory (or, much more likely,
dereferencing a garbage pointer and crashing).
Fixing both reveals another problem: the link input is an *archive*
consisting of multiple members, so we have to consider whether to check
all of them for the outdated-func-info thing we are checking here.
However, no compiler exists that emits a mixture of members with this
flag on and members with it off, and the linker always reserializes (and
upgrades) such things when it sees them: so all members in a given
archive must have the same value of the flag, so we only need to check
one member per input archive.

libctf: skip the testsuite from inside dejagnu
The libctf testsuite uses Tcl try/catch to trap run_output errors. This
is only supported in reasonably recent Tcls, so we detect the lack of
try/catch and suppress the testsuite via an Automake conditional in its
absence.
But this turns out not to work: Automake produces a check-DEJAGNU target
regardless of the value of this conditional and sticks it in an
unconditionally-executed part of the makefile, so the testsuite gets
executed anyway, and fails with a nasty-looking syntax error. We can't
disable it by taking "dejagnu" out of AUTOMAKE_OPTIONS, because if you
do that Automake stops you using RUNTEST, RUNTESTFLAGS and other
variables users would expect to work.
So move to disabling the testsuite from inside the testsuite itself,
importing the value of the former Automake conditional as a Tcl variable
and exiting very early in default.exp if it's false.
* configure.ac (TCL_TRY): No longer an Automake conditional.
Rename to...
(HAVE_TCL_TRY): ... this.
* Makefile.am: Drop TCL_TRY.
(development.exp): Set have_tcl_try.
* testsuite/config/default.exp: Exit if have_tcl_try is false.
* configure: Regenerated.
* Makefile.in: Likewise.

ctf: fix various dreadful typos in the ctf_archive format comments
When defining a format it helps to a) get the endianness right when you
explicitly state what it is and b) define things in terms of fields that
exist rather than fields that don't.

these comments...)
