Though, it hasn't been used before recent libstdc++ changes that actually call iconv functions. This now leads to failures exposed by running the test-suite, unless the newlib being used has been explicitly configured with --enable-newlib-iconv. When failing, there are undefined references to iconv, iconv_open or iconv_close for multiple tests. Thankfully there's a macro in newlib.h that we can check to detect presence of iconv support for the newlib build that's used. libstdc++-v3: PR libstdc++/116362 * configure.ac: Check newlib configuration whether iconv is enabled. * configure: Regenerate.
