[OE-core] [meta-oe]question about PMS

[Bian, Naimeng]

Hi all

By default, the value of PACKAGE_ARCH is set to TUNE_PKGARCH when building for the target, 
BUILD_ARCH when building for the build host and "${SDK_ARCH}-${SDKPKGSUFFIX}" when building for the SDK.

So, we will get the name of rpm package as the following in qemux86-64 build.
  - all/PKG-verskon.all.rpm
  - core2_64/PKG-version.core2_64.rpm
  - qemux86_64/PKG-verskon.qemux86_64.rpm

It's not friendly to work with yum. 

Why don't we make it same as deb-package which it gets the name of package as below.
  - all/PKG-verskon.all.rpm
  - core2-64/PKG-version.amd64.rpm
  - qemux86_64/PKG-verskon.amd64.rpm

Thanks
 Bian
