Bug description:
[ Impact ]
Glibc arch level is not recognized correctly on IBM z17 instances.
Add detection for machine types 0x9175 and 0x9176 and set ELF platform
name to z17.
[ Fix ]
Backport the following commit from upstream:
- 8231a0e63240 s390: Add z17 elf platform
[ Test Plan ]
Boot on a z17 instance and execute:
$ LD_SHOW_AUXV=1 id | grep AT_PLATFORM
This must return z17.
[ Where Problems Could Occur ]
The fix just adds some cases on a switch statement,
the regression potential therefore is really low.
