`single-executable-application-test*` fail on Linux ppc64le

This is similar to #59553, but for Linux ppc64le.

#58761 skipped several single-executable-application-test* tests on Linux ppc64le for Node.js 20.19.3 onwards:

test-single-executable-application
test-single-executable-application-assets
test-single-executable-application-assets-raw
test-single-executable-application-disable-experimental-sea-warning
test-single-executable-application-empty
test-single-executable-application-snapshot
test-single-executable-application-snapshot-and-code-cache
test-single-executable-application-snapshot-worker
test-single-executable-application-use-code-cache

There was an attempt to bisect during Node.js 20.19.3, but it was inconclusive (one bisect pointed to a WPT commit, a second bisect pointed to the release commit).

The same tests were skipped for Node.js 22.18.0 in #58914.

We're now seeing similar test failures when we build main with clang (the tests are currently passing when built with gcc).

In these cases the injected binary is crashing (SIGSEGV), e.g.

These appear to be consistent crashes and not flakes.

I tried to run one of the injected binaries through lldb, but it wasn't helpful(?):

[iojs@test-osuosl-rhel8-ppc64--le-4 sea]$ lldb ./sea
(lldb) target create "./sea"
Current executable set to '/tmp/sea/sea' (powerpc64le).
