This needs a wrapper script around find-debuginfo.sh, so that ld.so is not stripped. This commit resolves debuginfo file conflicts (#1886295) because the ldconfig debuginfo file now includes the architecture name. All debugging information is preserved in ld.so (#1905611). With the distribution defaults, we strip all binaries again (#1661510).

# Wrapper script for find-debuginfo.sh
|
|
#
|
|
# Usage:
|
|
# wrap-find-debuginfo.sh LDSO-PATH SCRIPT-PATH SCRIPT-ARGS...
|
|
#
|
|
# The wrapper saves the original versions of the file at LDSO-PATH,
|
|
# invokes SCRIPT-PATH with SCRIPT-ARGS, and then restores the
|
|
# LDSO-PATH file. As a result, LDSO-PATH has unchanged debuginfo even
|
|
# after debuginfo extraction.
