Hello,

For the multilib package like lib32-bash, its rpm package name
is bash-4.3.30-r0.lib32_x86.rpm, but for ipk and deb, its name is
lib32-bash.ipk and lib32-bash.deb, there is a side effect for
the naming of rpm, for example, if packagegroup-xx rdepends on bash,
the lib32-packagegroup-xx should rdepend on lib32-bash, but
the its rpm pkg knows nothing about lib32-bash, so it still rdepends
on bash, this causes 32bit toolchain libs not installed when export
multilib sdk, for example:

Configured multilib:
MACHINE ?= "qemux86-64"
require conf/multilib.conf
MULTILIBS = "multilib:lib32"
DEFAULTTUNE_virtclass-multilib-lib32 = "x86"

$ bitbake core-image-minimal -cpopulate_sdk

When PACKAGE_CLASSES = "package_rpm",  the lib32-libgcc,
lib32-libgcc-dev or other lib32-xx packages are not installed,
so that the 32bit toolchain doesn't work in SDK, this is because
lib32-packagegroup-core-standalone-sdk-target can't pull in the
lib32-xx correctly.

When PACKAGE_CLASSES = "package_ipk", it works well.

Does anyone why we don't use the name like lib32-bash.rpm, please ?
Can we use lib32-bash, please ?
