perf trampoline tests fail after BOLT optimizations

Bug report

Bug description:

As initially reported in https://github.com/python/cpython/pull/128845. The following tests fail

test_sys_api (test.test_perf_profiler.TestPerfTrampoline.test_sys_api) ... FAIL
test_trampoline_works (test.test_perf_profiler.TestPerfTrampoline.test_trampoline_works) ... FAIL

CPython main branch

Operating systems tested on:

Linux

Lib/test/test_perf_profiler.py から始め、BOLT 最適化後の Linux で失敗している 3 つの TestPerfTrampoline テストを再現してください。期待される perf シンボルが見つからない理由と、fork されたプロセスが -11 で終了する理由を追跡してください。test_sys_api、test_trampoline_works、test_trampoline_works_with_forks がパスすれば完了です。
