"make bin/smbtorture4" fails on FreeBSD 9

1. looking at lib/ccan/failtest/failtest.c shows that 'backtrace()' is
only used with this:

   #if HAVE_BACKTRACE
   #include <execinfo.h>
   ...

   That means we are likely to have configure tests.

2. searching for configure tests

   metze at SERNOX11:~/devel/samba/3.X/master3$ git grep 'backtrace' | grep
wscript
   lib/util/wscript_configure:# backtrace could be in libexecinfo or in libc
   lib/util/wscript_configure:conf.CHECK_FUNCS_IN('backtrace
backtrace_symbols', 'execinfo', checklibc=True, headers='execinfo.h')

   metze at SERNOX11:~/devel/samba/3.X/master3$ git grep 'backtrace' | grep
configure
   lib/util/wscript_configure:# backtrace could be in libexecinfo or in libc
   lib/util/wscript_configure:conf.CHECK_FUNCS_IN('backtrace
backtrace_symbols', 'execinfo', checklibc=True, headers='execinfo.h')
   source3/configure.in:# libexecinfo provides backtrace_symbols on FreeBSD
   source3/configure.in:AC_SEARCH_LIBS(backtrace_symbols, [execinfo])
   source3/configure.in:AC_CHECK_FUNCS(backtrace_symbols)

3. It's likely that there's a missing dependency to 'execinfo' in the
waf build

   metze at SERNOX11:~/devel/samba/3.X/master3$ find lib/ccan/ -name 'wscript*'
   lib/ccan/wscript

4. the 'build' section in 'lib/ccan/wscript' looks like this:

   def build(bld):
       bld.SAMBA_LIBRARY('ccan',
                      vnum="0.1-init-1161-g661d41f",
                      source=bld.path.ant_glob('*/*.c'),
                      private_library=True)

There's no dependency to 'execinfo'.

I've pushed the following commit to autobuild:
