indirect branch tracking(IBT) feature aiming to ensure the target address of an indirect jump/call is not tampered. When IBT is enabled, each function or target of any indirect jump/call will start with an 'endbr32/64' instruction otherwise the program will crash during execution. To build an application with CET enabled. we need to ensure: 1. build the source code with "-fcf-protection=full" 2. all the libraries linked with .o files must be CET enabled too This patch aims to enable CET for compiler-rt builtins library, we add an option "COMPILER_RT_ENABLE_CET" whose default value is OFF to enable CET for compiler-rt in building time and when this option is "ON", "-fcf-protection=full" is added to BUILTINS_CFLAG and the "endbr32/64" will be placed in the beginning of each assembly function. We also enabled CET for crtbegin, crtend object files in this patch.
