RFR : 8219746: Provide virtualization related info in the hs_error file on linux ppc64 / ppc64le

[Baesken, Matthias]

Hi David, thanks for the review .

I do not see the file  lparcfg  on our x86_64  and s390  Linux machines.

And

https://manpages.debian.org/testing/powerpc-ibm-utils/lparcfg.5.en.html

states :

"The lparcfg file is a virtual file which contains information related to an IBM Power Logical Partition."


So it seems that it is really  (IBM)   Power   (ppc64)  specific .

Best regards, Matthias
