mathworks_zynq_R19.2.1 is using a dead toolchain

[BaaBaaGoat]

mathworks_zynq_R19.2.1 cant build because it's using

BR2_TOOLCHAIN_EXTERNAL_PATH="/opt/Xilinx/SDK/2018.2/gnu/arm/lin
BR2_TOOLCHAIN_EXTERNAL_CUSTOM_PREFIX="$(ARCH)-xilinx-linux-gnueabi"

in buildroot/board/mathworks/zynq/defconfig/xilinx.config,
but arm-xilinx-eabi-gcc is the COdeSourcery toolchain, which is no longer available in SDK later than 2017.2.

@BaaBaaGoat have you fixed the problem? I changed the Toolchain to 2020.1 version (Linaro based) but i got another Error:
"Unable to detect the toolchain sysroot, Buildroot cannot use this toolchain.
"

Installing a linaro toolchain manually worked pretty good. In case someone is having the same issues
