Subject: Build support for s390x: Fix a few paltests (#53288)
X-Git-Tag: submit/tizen/20210909.063632~1131
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8eb13798e8b9033c995f7ea7ba2d4527089abe91;p=platform%2Fupstream%2Fdotnet%2Fruntime.git

Build support for s390x: Fix a few paltests (#53288)

* Accommodate platforms (like s390x) where the SIGSEGV fault address
  is only provided on a page granularity by the HW/OS

* All paltests now pass on s390x
