From 4f8126f3a665456b68ae923cd7a7e9b9eb98547d Mon Sep 17 00:00:00 2001 From: Willy Tarreau Date: Sat, 28 May 2022 17:45:46 +0200 Subject: [PATCH] tools/nolibc: add a help target to list supported targets The "help" target simply presents the list of supported targets and the current set of variables being used to build the sysroot. Since the help in tools/ suggests to use "install", which is supported by most tools while such a target is not really relevant here, an "install" target was also added, redirecting to "help".
