Subject: [PATCH 09/11] kselftest/arm64: mte: Makefile: Fix clang compilation
Date: Fri, 19 Mar 2021 16:53:32 +0000	[thread overview]
Message-ID: <20210319165334.29213-10-andre.przywara@arm.com> (raw)
In-Reply-To: <20210319165334.29213-1-andre.przywara@arm.com>

When clang finds a header file on the command line, it wants to
precompile that, which would end up in a separate output file.
Specifying -o on that same command line collides with that effort, so
the compiler complains:

clang: error: cannot specify -o when generating multiple output files

Since we are not really after a precompiled header, just drop the header
file from the command line, by removing it from the list of source
files in the Makefile.
