Hopefully, complete strip workaround
In stripping, /usr/bin/bash, /usr/bin/find, and /usr/bin/strip are
running. Strip them, and all libraries used by them in /tmp, then
install them back.
We can't use this for all libraries or binaries: the process above
discouples hard links (for example /usr/bin/perl and perl5.34.0). So
unfortunately the stripping instruction is now a stupidly long bash
script...
