Sorry, I don't know - but I bet it has to do with one of two things.
One is that you should use -T instead of -Wl,-T.  The other is that
you need to tell the GCC driver what target you're compiling for.
You want to run this on an STM32, so you need -mcpu=cortex-m3
-mthumb.  After that, it should select the correct libgcc.
