Severity: Standard
Applicable for: Wind River Linux 5
Component/s: Networking


Problem Description
For fsl-p50xx, default rootfs is 32bit, and kernel is 64bit. After get vmcore with kdump, the default
crash command can not analyse vmcore because they are different arch. In order to analyse vmcore,
user must build and install lib64-crash.
So if build MLIB, both lib64 crash and lib32 crash should be installed.

Expected Behavior
if build MLIB, both lib64 crash and lib32 crash should be installed.

Observed Behavior
root@localhost:~# file /usr/bin/crash
/usr/bin/crash: ELF 32-bit MSB executable, PowerPC or cisco 4500, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.34, with unknown capability 0x41000000 = 0x11676e75, with unknown capability 0x10000 = 0x90401, not stripped

Build MLIB crash manually 

Steps to Reproduce

1. Build MLIB rootfs
configure --enable-board=fsl-p50xx --enable-kernel=cgl --enable-rootfs=glibc_cgl --enable-parallel-pkgbuilds=8 --enable-jobs=8
make fs

configure --enable-board=intel-xeon-core --enable-kernel=cgl --enable-rootfs=glibc_cgl --enable-parallel-pkgbuilds=8 --enable-jobs=8
make MLIB=lib32 fs

2. Check lib32 crash and lib64 crash are all installed.
