[ptxdist] [PATCH v3] 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.

 CHANGES:
 -v2: select HOST_FLEX, drop 'v' from url version, update md5,
      use proper DTC_MAKE_ENV
 -v3: use ptx/nl, use osi-conform license
