There is an updated pull request by Logarithmus against master on the void-packages repository

https://github.com/Logarithmus/void-packages avra
https://github.com/void-linux/void-packages/pull/25942

New package: avra-1.4.2
Assembler for the Atmel AVR microcontroller family.
I had to explicitly specify commit hash, because 1.4.2 tag fails to build.
The author fixed it but didn't bump the version.

A patch file from https://github.com/void-linux/void-packages/pull/25942.patch is attached
