Mike Frysinger 96cdfef033 sim: headers: use abs_srcdir to find helper scripts
Trying to run `headers` in an out-of-tree build fails atm due to the
relative srcdir paths being used in a location other than where they
were setup to be used from.  Get abs_srcdir from configure and use
that instead where applicable.

Mike Frysinger b909d38dfa sim: erc32: fix linking against local readline on modern (ncurses) systems
The current erc32 configure script only searches for -ltermcap to provide
any termcap funcs (which readlines needs).  When building against a local
readline (which is static), we hit link failures like so:
  gcc ...-I/-D flags... -o sis \
    sis.o exec.o erc32.o func.o help.o float.o \
    ../../bfd/libbfd.a ../../opcodes/libopcodes.a \
    ../../libiberty/libiberty.a -lz -lnsl \
    ../../readline/libreadline.a -lm
  ../../readline/libreadline.a(display.o): In function 'cr':
  .../readline/display.c:2486: undefined reference to 'tputs'
  collect2: ld returned 1 exit status
  make[2]: *** [sis] Error 1

Use AC_SEARCH_LIBS from gdb's configure.ac as suggested by Joel Brobecker
to check for additional termcap providers.

ifdefs around a bunch of syscalls, so extend that style to cover the

Joel Brobecker 96987c2b7f Work around Solaris bourne shell limitation when building the sim
Building the sim on a sparc-solaris 2.8 machine fails when configured
with no extra sim hardware:

> for hw in  ; do \
>         echo "extern const struct hw_descriptor
>         dv_${hw}_descriptor[];" ; \
>       done >> tmp-hw.h
> echo 'const char version[] = "'"`sed q
> /[...]/../../gdb/version.in`"'";'
> >> version.c-tmp
> /bin/sh: -c: line 1: syntax error near unexpected token `;'
> /bin/sh: -c: line 1: `for hw in  ; do \'
> make[3]: *** [hw-config.h] Error 2

The same thing happens with the version of bash that we got from
Sun as well (which is very old: 2.03.0(1)-release).

The problems comes from the fact that both shells are buggy, and
reject the following script:

    for hw in ; do
      [...]
    done

The above is what sim/common/Makefile.in tries to execute when
generating hw-config.h.

In order to allow users to build out of the box on these machines,
this patch works around this bug.  It does rely on the fact that
none of the tokens in SIM_HW contain whitespaces.

        * Make-common.in (hw-config.h): Work around bug in Solaris 2.8
        system bourne shell.
