[PATCH 03/12] s390: purgatory: pass --target option to clang

From: Arnd Bergmann
Date: Mon Apr 08 2019 - 17:27:59 EST


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.
