Problem with building MbedTLS

Hi,
I would like to use mbedtls with my stm32f7 project - so I have to build these lib by arm-gcc.
I am trying do this, but still have problem.
my command to building: CC
CC=/home/jareeeeczek/Arczbit/Firmware/ProgramingRelated/ARM_GCC/gcc-arm-none-eabi-10-2020-q4-major/bin/arm-none-eabi-gcc cmake -DUSE_SHARED_MBEDTLS_LIBRARY=On …/

and my erros:

 "none-eabi-10-2020-q4-major/bin/arm-none-eabi-gcc cmake - 
 DUSE_SHARED_MBEDTLS_LIBRARY=On ../

/home/jareeeeczek/Arczbit/Firmware/ProgramingRelated/ARM_GCC/gcc-arm-none-eabi-10-2020-q4-major/bin/arm-none-eabi-gcc

is not able to compile a simple test program.

It fails with the following output:

arm-none-eabi-gcc: error: unrecognized command-line option '-rdynamic'

Anyone has idea why arm-gcc has problem with building test program?
my host is Ubuntu.
Best regards,
