linker error in CUBe bootloader

[mahowi]

When trying to compile the firmware for CUBe, compilation stops with a linker error at CUBe bootloader: /usr/lib/gcc/arm-none-eabi/7.3.1/../../../arm-none-eabi/bin/ld: section .ARM.exidx LMA [0011ccf0,0011ccf7] overlaps section .relocate LMA [0011ccf0,0011d25f] collect2: error: ld returned 1 exit status make[3]: *** [Makefile:125: CUBE_BL.elf] Fehler 1

Compiler version: arm-none-eabi-gcc (15:7-2018-q2-6) 7.3.1 20180622 (release) [ARM/embedded-7-branch revision 261907]

I got the same error. I also tried using an Docker container as build environment:

git clone https://github.com/heliflieger/a-culfw.git
cd a-culfw
docker run -it --rm -v $(pwd):/code stronglytyped/arm-none-eabi-gcc

Inside the container I ran:

/code/culfw/Devices/CUBe
make

The Error:

arm-none-eabi-gcc  -L/arm-none-eabi/lib -Os -fno-isolate-erroneous-paths-dereference -o CUBE_BL.elf

Solution but untested (according to this https://stackoverflow.com/questions/30778614/arm-none-eabi-ld-section-arm-exidx-overlaps-section-data) replace CUBE_flash.lds and CUBE_BLflash.lds with this: [CUBE.zip](https://github.com/heliflieger/a-culfw/files/9776197/CUBE_.zip) This avoids the linker error.

I have not tried this on my Max!Cube, yet!

If it works i will add a pull request!
