Configure fails for gcc10 but works fine for gcc9. Sierra 10.12.6, XCode 9.2.

Yes, this problem ​occurs on our buildbot too.

To be more precise:

​On 10.11 with Xcode 8.2.1 we saw:

 ld: file not found: /usr/lib/system/libsystem_symptoms.dylib for architecture x86_64

Both Xcode 8.2.1 and the corresponding command lines tools contain only the 10.12 SDK. The 10.12 SDK contains /usr/lib/system/libsystem_symptoms.tbd but OS X 10.11 itself does not contain /usr/lib/system/libsystem_symptoms.dylib.

On 10.12 with Xcode 9.2 you saw:

 ld: file not found: /usr/lib/system/libsystem_darwin.dylib for architecture x86_64

Both Xcode 9.2 and the corresponding command line tools contain only the 10.13 SDK. The 10.13 SDK contains /usr/lib/system/libsystem_darwin.tbd but macOS 10.12 itself does not contain /usr/lib/system/libsystem_darwin.dylib.

This makes me wonder if something—gfortran?—is looking at the SDK to determine what capabilities it should use, not taking into account that not all of the capabilities advertised by the SDK are actually available on the running OS.
