--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
libstdc++-v3/configure.ac has:
# Libtool setup.
if test "x${with_newlib}" != "xyes" && test "x${with_avrlibc}" != "xyes"; then
AC_LIBTOOL_DLOPEN
fi
AM_PROG_LIBTOOL
ACX_LT_HOST_FLAGS
AC_SUBST(enable_shared)
AC_SUBST(enable_static)
Since I actively avoid understanding what libtool actually does I have no idea
if/when we can make that AM_PROG_LIBTOOL conditional. Libstdc++ doesn't use
dlopen, so maybe we can just add --disable-dlopen. Or maybe --disable-shared
should imply --disable-dlopen.
