$NetBSD: patch-src_tools_rust-installer_install-template.sh,v 1.8 2021/11/20 16:09:46 he Exp $

No logging to 'install.log'.
Do not create 'uninstall.sh'.

Rewrite to not use a whole lot of subprocesses just for doing
pattern matching and substitution in the install phase using "grep"
and "sed" when shell builtin "case" and "omit shortest match" ops
should do just fine.
