  tcmalloc RSEQ ABI violation causes crashes on linux kernel 6.19+

Bug description:
  With the 6.19 release of the Linux kernel, upstream MongoDB now
  experiences crashes after ~30 seconds due to an RSEQ error from
  tcmalloc. The unit test
  //tcmalloc/testing:background_test_no_glibc_rseq notably also fails on
  6.19 and 7.0, and may be due to the following commit -
  https://lore.kernel.org/all/20251027084307.578058898@linutronix.de/

  While mongodb is not supported in the Ubuntu archive, there are other
  packages using tcmalloc such as mysql-8.4 which may be affected.
