libgcc14 won't build on macOS Sequoia 15.0

[BarneyStratford]

From the build log: configure:3813: /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_lang_gcc14/libgcc14/work/build/./gcc/xgcc -B/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_lang_gcc14/libgcc14/work/build/./gcc/ -B/opt/local/aarch64-apple-darwin24/bin/ -B/opt/local/aarch64-apple-darwin24/lib/ -isystem /opt/local/aarch64-apple-darwin24/include -isystem /opt/local/aarch64-apple-darwin24/sys-include -fno-checking -c -g -O2 -pipe -Os -isysroot/Library/Developer/CommandLineTools/SDKs/MacOSX15.sdk conftest.c >&5 clang: error: no input files

It seems that configure.pipe causes this build failure in libgcc14. I've tried adding "configure.pipe no" to the portfile, and it does now build, but I'm not sure of the correct way to go about this.

My system is a vanilla install, with MacPorts 2.10.1, Xcode 16 and the equivalent developer tools. No idea if this problem exists on prior versions of macOS.
