[Bug 1979319] [NEW] Avoid using up static TLS surplus in glibc-2.27 in Ubuntu 18.04

[Steve Capper]

Public bug reported:

Hello,
A bug has been fixed in glibc 2.32 that prevented certain combinations of libraries loading that employed TLS.

https://sourceware.org/bugzilla/show_bug.cgi?id=25051

The glibc-2.31 in Debian Bullseye has been fixed with a similar bug raised at:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=964141

Specifically the Debian package employed the following patchies:
https://salsa.debian.org/glibc-team/glibc/-/blob/bullseye/debian/patches/any/git-surplus-tls-accounting.diff

Could that patch please also be picked up by the glibc-2.27 package in
Ubuntu 18.04?

FWIW, in addition to the Debian patches, I had to cherry-pick the following additional commits from upstream to allow this to work on Ubuntu 18.04:
3b856d093f elf: Ignore LD_AUDIT interfaces if la_version returns 0 [BZ #24122]
94b63e6620 support: Implement xdlmopen

Cheers,
