Re: Link tests after GCC_NO_EXECUTABLES

Jie started the thread back in September, and posted the following call
trace:
"libstdc++-v3/configure.ac" AM_PROG_LIBTOOL -> "libtool.m4" LT_INIT ->
_LT_SETUP -> _LT_LANG_C_CONFIG -> LT_SYS_DLOPEN_SELF
which leads to
checking for shl_load... configure: error: Link tests are not allowed
after GCC_NO_EXECUTABLES.
make[1]: *** [configure-target-libstdc++-v3] Error 1
Jie had a patch for that, but I decided to fix it by just making things
link, since I've seen other occurrences of this problem over the years.
It just seems more robust not to require the configure scripts to avoid
linking.
