 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.
