Subject: [PATCH v3 05/12] selftests/nolibc: allow customize CROSS_COMPILE by architecture
Date: Fri, 28 Jul 2023 04:27:10 +0800	[thread overview]
Message-ID: <b5e181d8dd12d48a17199df2e11da9e0e82065b2.1690489039.git.falcon@tinylab.org> (raw)
In-Reply-To: <cover.1690489039.git.falcon@tinylab.org>

Some cross compilers may not just be prefixed with ARCH, customize them
by architecture may simplify the test a lot, especially, when iterate
with ARCH.

After customizing this for every architecture, the minimal test argument
will be architecture itself, no CROSS_COMPILE required to be passed.

If the prefix of installed cross compiler is not the same as the one
customized, we can also pass CROSS_COMPILE as before or even pass
CROSS_COMPILE_<ARCH>.
