[ptxdist] [PATCH v2] dtc: new package

[Ladislav Michl <oss-lists@triops.cz>]

From: Ladislav Michl <ladis@linux-mips.org>

Please note this package is not as symmetrical as the typical
host-* and normal variants. Here the latest version is usually
needed.

This work is prepping for qemu 8.2.0+, as it requires libfdt
as a separate library. It has stopped providing one internally.
