Hi Dave,
I didn't explain about background issues.
I built a PPC binary on an x86 host cross compiler. When run it,
I have to ftp to PPC machine where dose not have self build tools.
Here is dumping my build environment info.
$ uname -m
x86_64
$ file gcc
gcc: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV),
dynamically linked (uses shared libs), for GNU/Linux 2.2.5, stripped

This "target=PPC" on a PPC64 host has been already supported
since I copied it into ppc[] table.
[PATCH v1 1/4] Support PPC32 Core analysis on PPC64 Host
https://www.redhat.com/archives/crash-utility/2011-November/msg00019.html
The purpose is to build ppc 32bit binary with compatible target CFLAGS "-m32"
of ppc64 compiler. This is similar idea with x86_64.
But I added new cross support(is_cross is TRUE) in patch#5 which is
distinct from original purpose.
+ {
+ .host = X86,
+ .cflags = "-D_FILE_OFFSET_BITS=64",
+ .gdb_conf_flags = "--host=i686-pc-linux-gnu "
+ "--target=powerpc-elf-linux",
+ .is_cross = TRUE,
+ },

My issues are to arrange original crash package as compilable one with cross.
I edit package's Makefile or configure parameters --host/--target at spec file,
finally building with environment variables CC, AR, LD, etc.
By applying patches, I can build crash only with tiny spec update,
"make target=PPC host_cross=X86" without modification of released archive.
Then, I'll start mips architecture (seems to go toward embedded minority).
There are probably the similar considerations about cross compile.
I want to be done with "make target=MIPS host_cross=X86" by adding mips tables.

I haven't caught this update. I'd send updated portion.
Thanks,

Subject: [PATCH 2/5] Makefile: wrap cc, gcc and ar with common make variables
By this variables, cross-compiler can be adapted into crash build
and also, don't hurt existing build targets.
CC or AR must be guaranteed by cross environ.
A configure.c is still compiled with host native compiler
because this need to run before crash compile.
