Subject: [PATCH 03/12] s390: purgatory: pass --target option to clang
Date: Mon,  8 Apr 2019 23:26:16 +0200	[thread overview]
Message-ID: <20190408212648.2407234-3-arnd@arndb.de> (raw)
In-Reply-To: <20190408212648.2407234-1-arnd@arndb.de>

The purgatory Makefile does not inherit the original cflags,
so clang falls back to the default target architecture when
building it, typically this would be x86 when cross-compiling.

Pass --target=s390x-linux to all compilers that understand
this option.
