Language model using clangd fails for embedded device using little big tune

Languagemodel breaks and creator cannot propertly parse completely valid c++ code (same code works for other target kits) for Aarch64 target which has been configured with "-mcpu=cortex-a72.cortex-a53". This includes our Boot2Qt iMX8QM (mek). 

When creator "parses" code for which above kit has been selected following error are visible in "General messages" tab:

LanguageClient clangd for qbench: Error -32001: invalid AST
LanguageClient clangd for qbench: Error -32001: invalid AST

Issue might be related to clang support for little big architecture:
