[ptxdist] [PATCH] ptxd_install_compression_format: don't use host readelf to figure out debug compression format

[Marc Kleine-Budde <mkl@pengutronix.de>]

The host readelf might be too old and doesn't understand the
compression formats of new toolchain libraries. This leads to the
following error:

| readelf: Warning: section '.debug_str' has unsupported compress type: 2

Use coss-readelf of toolchain instead.

Fixes: baf33e7186cb ("ptxd_install_file_extract_debug: pick the debug compression format from the toolchain")
