Test failure

glibc test stdlib/test-bz22786 fails with:

Didn't expect signal from child: got `Killed'

Initial RCA on renesas-rcar-s4-20.auto.eng.bos2.dc.redhat.com shows OOM killer terminates process.
RCA included checking out release/2.41/master (closest to upstream without a later gcc requirement) and running the test.

Goal

• follow up glibc test failure analysis, we discovered stdlib/test-bz22786 failure on RHIVOS automotive boards is caused by an out of memory condition, due to the test requirement of at least 4GB, which is more than the Renesas rcar-s4 board have available. per conversation with lpellecc and codonell, the conclusion is as following:
  the test should be marked as UNSUPPORTED on RHIVOS boards with less than 4GB RAM

Acceptance criteria

• stdlib/test-bz22786 is marked UNSUPPORTED instead of failing, while executed on boards with insufficient RAM
• System logs may include OOM messages and RHIVOS may need to adjust their own validators to account for that.
