From 9e90efa52ec3fd2d62b59488a1b347a55d356234 Mon Sep 17 00:00:00 2001 From: Frank Hunleth Date: Sat, 18 Feb 2017 16:01:11 -0500 Subject: [PATCH] erlang: set ERL_TOP to avoid using user's version Explicitly set the ERL_TOP environment variable to override values set on a user's system. This prevents Erlang's configure scripts from using source files outside of the ones that Buildroot downloaded.
