sorry, my fault -- forgot to rebuild the whole project.
Everything works fine with enabled FPU (-mthumb -mcpu=cortex-m4
-mfpu=fpv4-sp-d16 -mfloat-abi=hard)

yes, I know, I just checked that behavior is the same as before.
With these flags -mthumb -mcpu=cortex-m4 -mfpu=fpv4-sp-d16 -mfloat-abi=hard
I got error from linker:
/home/midnight/rtems/toolchain/5/lib/gcc/arm-rtems5/7.4.1/../../../../arm-rtems5/bin/ld:
error: o-optimize/test.exe uses VFP

Hello Sebastian,
I have added my own BSP for stm32l4 it based on stm32f4. If you want
you can take a look on it -- in attached my patch for a new BSP(stm32l4).
Due to the multilib changes, you have to adjust the GCC options for your
BSP:
