appimagetool follows symlinks outside of the AppImage for determining architecture

@teras when packaging an AppImage that contains a WINEPREFIX which links outside of the AppImage, then it tries to determine architectures outside of the AppImage.

It should not follow symlinks to determine the architecture, let alone symlinks that point to the outside of the AppImage.

Add a test for G_FILE_TEST_IS_SYMLINK ?

Yes, sounds like it. Can you send a PR? Thanks.

@probonopd this has been high priority for over half a year, but it hasn't been fixed by anyone, nor has anyone ever reported the same issue. Removing the tag therefore.

May be a low-hanging fruit for a first time contributor :-)
