Subject: [PATCH v1 3/4] selftests/nolibc: customize CROSS_COMPILE for loongarch
Date: Sun,  6 Aug 2023 03:49:35 +0800	[thread overview]
Message-ID: <d38f1fa6dec5ebb7ac4d54c728edb6d70cee3008.1691263493.git.falcon@tinylab.org> (raw)
In-Reply-To: <cover.1691263493.git.falcon@tinylab.org>

Loongarch is a fresh new architecture, there is no prebuilt toolchain
from most of local software repositories, let's use the one from [1].
