fe34861780 sim: nrun: add local strsignal prototype 
While libiberty provides a definition for this for systems that lack
the function (e.g. Windows), it doesn't provide a prototype.  So add
our own local copy in the one file that uses the func.

66d055c754 sim: enable hardware support by default 
Force this on for all ports.  We have a few common models that can
be used, so make them generally available.  If the port doesn't use
any hardware (the default), then behavior is unchanged.

9d90335212 sim: simplify hardware m4 macro 
Every port using this sets the 1st arg to yes and the 2nd arg to "".
These are the defaults we probably want anyways in order to unify the
codebase, so move them to the macro and only allow ports to declare
extra hardware models.

19f6a43c6c Do not check for sys/time.h or sys/times.h 
This updates the sim so that it unconditionally uses sys/time.h.  This
is in agreement with existing code, and a recent change to BFD.

I also think that sys/times.h is never needed by the sim, so this
patch removes the check and the one spot that was conditionally
including it.

efd82ac7cb Require GNU make 
GDB has required GNU make for quite some time, and this patch applies
this approach to the sim as well.  Requiring GNU make means that
automatic dependency tracking can be simple and reliable, and it also
makes other refactorings simpler.

1f195bc327 sim: use -Werror when probing for supported warning flags 
When building with clang, we get:

    error: unknown warning option '-Wmissing-parameter-type' [-Werror,-Wunknown-warning-option]

This is because clang only warns by default when encountering an unknown
warning option, and the probe for supported warning flags is done
without -Werror.  All flags are therefore accepted by configure, but
then it breaks when actually compiling a source file with -Werror.

This is equivalent to this commit in gdb:

    3e019bdc20
    gdb: Use -Werror when checking for (un)supported warning flags

We then see some other compilation errors when building with clang and
-Werror, they can be dealt with later.

37e9f18266 sim: switch to AC_CHECK_FUNCS_ONCE & merge a little 
This avoids duplicate tests for functions between common m4, arches,

Also manually delete known duplicate function tests between the m4,
bfin, and v850 ports.

a3e2cc64a6 sim: use AC_CHECK_TOOL to find ar 
Rather than require $AR be set and then default to `ar`, use the
standard AC_CHECK_TOOL helper to find a good prefixed tool.  In
practice this shouldn't change much as we seem to have macros in
the tree that were already setting it up, but we shouldn't rely
on that implicitly.

ebe9564b99 sim: require AC_PROG_CPP explicitly 
All the scripts were using this implicitly already, so there's no real
change for them, but we want to call it explicitly as the CPP tool is

760b3e8bc9 sim: common: split up acinclude.m4 into individual m4 files 
This file is quite large and is getting unmanageable.  Split it apart
to follow aclocal best practices by putting one-macro-per-file.  There
shouldn't be any real functional changes here as can be seen in the
configure script regens.
