Error when building for DSPIC33EV256GM106.

[Harish-00774]

Describe the bug
Building the hello world sample for DSPIC33EV256GM106 with XC-16 Toolchain gives an error. See logs below.

I'm on Windows V.Scode on a Lenovo.

To Reproduce
Steps to reproduce the behavior:

Follow the steps for Windows in [Getting Started] and related Architecture and Toolchain docs.
Activate Virtual Env.
Go to ~/<zephyr_repository
Run west build -p -b dspic32ev256gm106 samples/hello_world

See the error in the logs output of this report.
Expected behavior
I would expect it to build like it does when I build for SAML21_XPRO.

Impact
Blocking learnings about Zephyr OS

Where did you obtain this version of Zephyr? The "dspic33ev256gm106" is not present in upstream main branch. Also, what is the "XC-16" toolchain, you mention?

[ks-bobban]

1. We are developing the Zephyr RTOS for dspic mcu (dspic33ev256gm106). We got the Zephyr RTOS SDK from git hub and the version is zephyr-sdk-0.16.5-1.
2. The "dspic33ev256gm106" is not present in upstream main branch- Yes (Developed from our side)
3. Microchip XC16 Compiler version 2.10 . It's free compiler and we can use in MPLABX IDE.

Converting to discussion as this is not an issue with upstream Zephyr, but rather an issue with a downstream added board and toolchain.
