Rather than manually include tconfig.h when we think we'll need it (which
is error prone as it can define symbols we expect from config.h), have it
be included directly by config.h. Since we know we have to include that
header everywhere already, this will make sure tconfig.h isn't missed.
It should also be fine as tconfig.h is supposed to be simple and only set
up a few core defines for the target.
This allows us to stop symlinking it in place all the time and just use
it straight out of the respective source directory.
We want people to stop using the run.c frontend, but it's hard to notice
when it's still set as the default. Lets flip things so nrun.c is the
default, and users of run.c will get an error by default. We turn that
error into a warning for existing sims so we don't break them -- this is
mostly meant for people starting new ports.
Directories that don't use libtool need to add -ldl (on most *nix
hosts) to provide dlopen for libbfd.
config/
* plugins.m4 (AC_PLUGINS): If plugins are enabled, add -ldl to
LIBS via AC_SEARCH_LIBS.
gdb/
* acinclude.m4 (GDB_AC_CHECK_BFD): Don't add -ldl.
* config.in: Regenerate.
sim/ppc/
* configure.ac: Invoke AC_PLUGINS.
* config.in: Regenerate.
and regen lots of configure files.
It is rare for people to want to modify the cmd arg. In general, they
really shouldn't be, but a few still do. For those who misbehave, dupe
the string locally so they can bang on it.
I noticed the sim code is using an old implementation of the maintainer logic.
I cut it over to the new macro (like gdb has been doing). In practice, it
makes no difference currently as nothing in the sim tree uses it, but I have a
follow up commit for the Blackfin tree that needs it.
Before POSIX standardized strsignal(), old systems would hide the
prototype unless the normal extension defines were enabled. So use
the AC_USE_SYSTEM_EXTENSIONS helper for that.
Then make sure we include string.h ourselves in nrun.c rather than
relying on implicit includes via other sim headers.

Lift the code that GDB is using to generate dependencies on the fly and
port it over to the sim. Now people shouldn't have to manually maintain
these in their Makefile's.

Automake likes to dump macros automatically used into the aclocal.m4
file, but the common/aclocal.m4 naming prevents that. So rename it
to the more normal "acinclude.m4" so the aclocal tool can work.

Now that the sourceware tree generally requires autoconf-2.64, update
the sim tree to require that too.
This allows us to drop the long standing SIM_AC_COMMON/common.m4
workaround as autoconf 2.64+ seems to work for me.

For the ports that don't use the common/ subdir, we need to add stub funcs
to them to avoid build failures with gdb and command completion. These do
not implement the actual completion functionality ... any port that wants
that can either convert to the common/ subdir, or fill out the function on
their own time.

As pointed out by Sandra Loosemore, a bunch of targets define sim_write
themselves instead of using the common/ code. So constify them too.
