Cannot find -lrt and -lpthread during make build for coremark-pro with "gcc-arm-none-eabi-10.3-2021.10"

SDogra

Not able to make CoreMark-Pro build with "gcc-arm-none-eabi-10.3-2021.10". 

CoreMark®-PRO (2015) is an industry-standard benchmark that measures the multi-processor performance of central processing units (CPU) and embedded microcrontrollers (MCU) 

github.com/.../coremark-pro

I changed gcc64.mak and common.mak file to add gcc-arm-none-eabi-10.3-2021.10 path. 

Changes mainly for below lines:
TOOLS = ./coremark-pro-main/gcc-arm/x86_64/gcc-arm-none-eabi-10.3-2021.10
CC = $(TOOLS)/bin/arm-none-eabi-gcc
AS = $(TOOLS)/bin/arm-none-eabi-as
LD = $(TOOLS)/bin/arm-none-eabi-gcc
AR = $(TOOLS)/bin/arm-none-eabi-ar
INCLUDE = $(TOOLS)/arm-none-eabi/include

ARM gcc-arm-none-eabi-10.3-2021.10 package installed from ARM download link

Command= make TARGET=linux64 build-all
