libgcc14 (libgcc14-14.2.0_1+stdlib_flag.darwin_24.arm64.tbz2) failed to build with config error ("configure: error: cannot compute suffix of object files: cannot compile") on macOS Sequoia beta 15.0 Beta (24A5327a)

[avisformosa]

Dear MacPorts community! As described above I negligently updated to the beta of Sequoia (15.0 Beta (24A5327a)). As far as I can tell, the Xcode beta and the Command Line Tools are up to date with the beta, and most things compile without problems, but unfortunately, libgcc fails with the following error:

Any suggestions or is this a generic bug as the "configure: error: cannot compute suffix of object files: cannot compile"-Error is somewhat general - but I did not find any useful work around. Thanks!
