[ptxdist] [PATCH] ptxd_install_compression_format: handle no debug compression

[Ladislav Michl]

From: Ladislav Michl <ladis@triops.cz>

Some toolchains do not compress debug sections causing later objcopy
failure such as:
aarch64-linux-gnu-objcopy: unrecognized --compress-debug-sections type `'

You're not the only one that found this.. I have a slightly more compact

I'm happy with whatever working version :) I've replaced
scripts/lib/ptxd_make_xpkg_pkg.sh in my BSP with fixed
version, so there is no rush.
