Subject: [PATCH 2/3] pc-bios/s390-ccw/Makefile: Check more compiler flags for Clang
Date: Wed, 12 May 2021 19:15:49 +0200 [thread overview]
Message-ID: <20210512171550.476130-3-thuth@redhat.com> (raw)
In-Reply-To: <20210512171550.476130-1-thuth@redhat.com>
Older versions of Clang do not like -fno-delete-null-pointer-checks
or -msoft-float. So let's add a proper check for those.
