crash: Fix cross compilation for 32-bit arm

Browse Source 
The upstream crash Makefile CONF_TARGET_ARCH mapping (used when
CROSS_COMPILE is set) enumerates most of OE supported arches
but omits 32-bit arm. Building with CROSS_COMPILE=arm-*
therefore aborts at Makefile parse time:

    Makefile:75: *** The current Arch(arm) does not support cross compilation.  Stop.

ARM is already a valid crash target (defs.h/configure.c), so add a patch
mapping the normalized "arm" arch to CONF_TARGET_ARCH=ARM like every
other supported arch.

Verified by cross building crash for qemuarm (arm-yoe-linux-gnueabi-):

Subject: [PATCH] Makefile: support cross compiling for 32-bit arm
The CONF_TARGET_ARCH cross-compilation mapping enumerates aarch64,
s390x, powerpc64, ppc64le, alpha, i386, mips, sparc64 and riscv64 but
omits 32-bit arm. As a result, building with CROSS_COMPILE=arm-* (e.g.
arm-poky-linux-gnueabi-) aborts at Makefile parse time with:
Makefile:75: *** The current Arch(arm) does not support cross compilation. Stop.
ARM is already a valid crash target (defs.h/configure.c), so map the
normalized "arm" arch to CONF_TARGET_ARCH=ARM like every other arch.
