Chromium Cross Compilation Build Failures - meta-clang and gn-native

Hello,

I am trying to compile meta-chromium (cross compilation for Qualcomm SoC) but getting build errors for meta-clang and gn-native as mentioned below -

gn-native error - clang++ -target x86_64-linux -MMD -MF src/gn/bundle_data.o.d -I../../../tools/gn/src -I. -isystem/<>/build-qti-distro-rb-debug/tmp-glibc/work/x86_64-linux/gn-native/105.0.5195.102-r0/recipe-sysroot-native/usr/include -Og -g -feliminate-unused-debug-types -pipe -isystem/<>/build-qti-distro-rb-debug/tmp-glibc/work/x86_64-linux/gn-native/105.0.5195.102-r0/recipe-sysroot-native/usr/include -Og -g -feliminate-unused-debug-types -pipe -D_LIBCPP_HAS_NO_VENDOR_AVAILABILITY_ANNOTATIONS -DNDEBUG -O3 -fdata-sections -ffunction-sections -Werror -D_FILE_OFFSET_BITS=64 -DSTDC_CONSTANT_MACROS -DSTDC_FORMAT_MACROS -pthread -pipe -fno-exceptions -fno-rtti -fdiagnostics-color -Wall -Wextra -Wno-unused-parameter -Wextra-semi -Wundef -std=c++17 -c ../../../tools/gn/src/gn/bundle_data.cc -o src/gn/bundle_data.o error: unable to create target: 'No available targets are compatible with triple "x86_64-unknown-linux"'

Could you please provide any pointer / guidance to me for the above mentioned errors.

Here are more details of the build environment - OS - Yocto Dunfell HW - Qualcomm SoC (aarch64) Host - x86 Ubuntu 18.04
