Upstream commit: aa601d024424c40ae9a69b0c4e394a70ea0570c8

Several upstream commits change NEWS only (changes we do not backport)
or have been backported before, which is why there are gaps.

- x86: Use CHECK_FEATURE_PRESENT to check HLE [BZ #27398]
- x86: Filter out more Intel CPUs for TSX [BZ #27398]
- Fix glibc 2.34 ABI omission (missing GLIBC_2.34 in dynamic loader)
