Richard would like to make GCC configure fatal by default unless users
have safe glibc or explicitly ask for it:

This patch set backports GLIBC_ABI version dependencies to 2.45 so that we
can tell users to use it.

H.J. Lu (3):
  x86: Add GLIBC_ABI_GNU2_TLS version dependency
  x86-64: Add GLIBC_ABI_DT_X86_64_PLT version dependency
  i386: Add GLIBC_ABI_GNU_TLS version dependency
