Subject: [PATCH v2 2/9] configure: cross-compiling without cross_prefix
Date: Sun, 18 Oct 2020 18:39:21 -0700	[thread overview]
Message-ID: <20201019013928.72770-3-j@getutm.app> (raw)
In-Reply-To: <20201019013928.72770-1-j@getutm.app>

From: osy <osy86@users.noreply.github.com>

The iOS toolchain does not use the host prefix naming convention. We add a
new option `--enable-cross-compile` that forces cross-compile even without
a cross_prefix.
