Compilation error with ARM Compiler 6

[sreeramIfx]

Describe the bug
Compiling blinky with GCC works fine, but the same app compiled with ARM Compiler 6 fails with the below described error when linking.

C:\WINDOWS\system32\cmd.exe /C "cd . && C:\workspace\ArmCompilers\bin\armlink.exe  --cpu=cortex-m4   --via=CMakeFiles\zephyr_pre0.rsp -o zephyr\zephyr_pre0.elf && C:\WINDOWS\system32\cmd.exe /C "cd /D C:\workspace\gitlab\zephyrproject-rtos\zephyr\build\zephyr && "C:\Program Files\CMake\bin\cmake.exe" -E true""
Error: L6384E: No Load Execution Region of name bss seen yet at line 11.
Error: L6384E: No Load Execution Region of name bss seen yet at line 15.

The errors seems to be from the below lines (not able to find __bss_start symbol) in the cmake\linker_script\arm\linker.cmake. I am able to work-around the errors by hardcoding instead of using __bss_start

zephyr_linker_symbol(SYMBOL __kernel_ram_start EXPR "(@__bss_start@)")
zephyr_linker_symbol(SYMBOL __kernel_ram_end  EXPR "(${RAM_ADDR} + ${RAM_SIZE})")
zephyr_linker_symbol(SYMBOL __kernel_ram_size EXPR "(@__kernel_ram_end@ - @__bss_start@)")

To Reproduce
Steps to reproduce the behavior:

1. $Env:ZEPHYR_TOOLCHAIN_VARIANT="armclang"
2. west build -p always -b cy8cproto_063_ble .\samples\basic\blinky\

Expected behavior
blinky should compile and link successfully with ARM compiler as well

Impact
Unable to use ARM Compiler for our platforms

I am also seeing the issue described @ #41435 (reply in thread)

I am able to work around the issue by using -DCONFIG_OUTPUT_DISASSEMBLY=n (as described in the above link). But its indicated that it should not happen with versions > 6.17 I am seeing it with ver 6.22 as well
