Hi Raman,
Thank you for reviving this discussing (I'm CC NuttX mailing list
because it could interest one person or two).

Nice, I duplicated it here and confirmed it "works"
I cloned your repo [2] and copied it to /opt/avr32 and setup my PATH with it.
Then I run:
$ ./tools/configure.sh avr32dev1:nsh
And:
$ make
Create version.h

Oh, I think you missed to enable CONFIG_DEBUG_SYMBOLS at menuconfig:
Build Setup --->
Debug Options --->
[*] Generate Debug Symbols
Then I can see the debug_info are included:
$ file nuttx
nuttx: ELF 32-bit MSB executable, Atmel 32-bit family, version 1
(SYSV), statically linked, with debug_info, not stripped

Yes, I used WSL in the past with STM32, ESP32 and XMC4, etc and it worked.

I don't use Windows, but yes I think the issue is related to
Unix/Windows directories delimitator: "\" vs "/", etc.
I think there is some configuration on Cygwin to improve Linux/Unix
compatibility.

I think adding the AVR32 support to CI will be very good to keep the
platform supported in the future.
BTW, if you saw the LED turned ON, it means that probably the NSH is
starting (otherwise you should see the LED blinking).
Do you think it is possible to gdb OpenOCD + GDB working for this MCU?
