Thank you very much for this hint. It saved me a lot of time.

It had something to do with the dot-symbols. I added

+/* Simplified copy and paste from linux64.h and freebsd64.h */
+#undef DOT_SYMBOLS
+#define DOT_SYMBOLS 0
+

to the GCC configuration and now this strange linker behaviour is gone.

Unfortunately, it didn't fix the issue with -mcmodel=medium:
