Turns out that objdump is important and makes the
distinction in my context . . .

work/gcc-8.4.0/config/gcc-plugin.m4 has:

. . .
AC_DEFUN([GCC_ENABLE_PLUGINS],
  [# Check for plugin support
   AC_ARG_ENABLE(plugin,
   [AS_HELP_STRING([--enable-plugin], [enable plugin support])],
   enable_plugin=$enableval,
   enable_plugin=yes; default_plugin=yes)

   pluginlibs=
   plugin_check=yes

   case "${host}" in
. . .
     *)
       if test x$build = x$host; then
         export_sym_check="objdump${exeext} -T"
       elif test x$host = x$target; then
         export_sym_check="$gcc_cv_objdump -T"
       else
         export_sym_check=
       fi
     ;;
   esac
. . .
   if test x"$enable_plugin" = x"yes" -a x"$plugin_check" = x"yes"; then

     AC_MSG_CHECKING([for exported symbols])
     if test "x$export_sym_check" != x; then
       echo "int main() {return 0;} int foobar() {return 0;}" > conftest.c
       ${CC} ${CFLAGS} ${LDFLAGS} conftest.c -o conftest$ac_exeext > /dev/null 2>&1
       if $export_sym_check conftest$ac_exeext | grep foobar > /dev/null; then
         : # No need to use a flag
         AC_MSG_RESULT([yes])
       else
         AC_MSG_RESULT([yes])
         AC_MSG_CHECKING([for -rdynamic])
         ${CC} ${CFLAGS} ${LDFLAGS} -rdynamic conftest.c -o conftest$ac_exeext > /dev/null 2>&1
         if $export_sym_check conftest$ac_exeext | grep foobar > /dev/null; then
           plugin_rdynamic=yes
           pluginlibs="-rdynamic"
         else
           plugin_rdynamic=no
           enable_plugin=no
         fi
         AC_MSG_RESULT([$plugin_rdynamic])
       fi
     else
       AC_MSG_RESULT([unable to check])
     fi
. . .

But (both the poudriere-devel based build and the portmaster
build show such so I picked to show just one):

/wrkdirs/usr/ports/devel/aarch64-none-elf-gcc/work/.build/gcc/config.log:gcc_cv_objdump=/usr/local/aarch64-none-elf/bin/objdump
/wrkdirs/usr/ports/devel/aarch64-none-elf-gcc/work/.build/gcc/config.log:gcc_cv_objdump='/usr/local/aarch64-none-elf/bin/objdump'
/wrkdirs/usr/ports/devel/aarch64-none-elf-gcc/work/.build/gcc/config.cache:gcc_cv_objdump=${gcc_cv_objdump=/usr/local/aarch64-none-elf/bin/objdump}

Under poudiere-devel there is no /usr/local/aarch64-none-elf/bin/objdump path.
Under make/portmaster there may be an old /usr/local/aarch64-none-elf/bin/objdump path.

In my environments (showing one example context):

# ls -ldT /usr/local/aarch64-none-elf/bin/objdump
-r-xr-xr-x  2 root  wheel  8593272 Jan 30 01:05:50 2020 /usr/local/aarch64-none-elf/bin/objdump

So in portmaster (or make) the old /usr/local/aarch64-none-elf/bin/objdump
is used but in poudriere the path used fails and that failure is not
handled distinctly as "objdump tool missing".

It looks like devel/aarch64-none-elf-gcc/Makefile would need
changes for WITHOUT_BINUTILS= contexts in order to make sure
that an objdump exists via a known/used path, including in
poudriere based builds.
