config: Fix host -rdynamic detection for build != host != target
The GCC_ENABLE_PLUGINS configure logic for detecting whether -rdynamic
is necessary and supported uses an appropriate objdump for $host
binaries (running on $build) in cases where $host is $build or
$target.
However, it is missing such logic in the case where $host is neither
$build nor $target, resulting in the compilers not being linked with
-rdynamic and plugins not being usable with such a compiler. In fact
$ac_cv_prog_OBJDUMP, as used when $build = $host, is always an objdump
for $host binaries that runs on $build; that is, it's appropriate to
use in this case as well.
Tested in such a configuration that it does result in cc1 being linked
with -rdynamic as expected. Also bootstrapped with no regressions for
x86_64-pc-linux-gnu.
config/
* gcc-plugin.m4 (GCC_ENABLE_PLUGINS): Use
export_sym_check="$ac_cv_prog_OBJDUMP -T" also when host is not
build or target.
gcc/
* configure: Regenerate.
libcc1/
* configure: Regenerate.
