  * d/p/0009-Ada-select-64-bits-time-functions-from-GNU-libc-when.diff:
    Adjust for the new glibc behaviour of defining __USE_TIME_BITS64 also
    on native 64-bits platforms (Simon Chopin). Addresses: #1074577.
    LP: #2071605.
  * Pass --package-metadata on distros with supporting linkers (starting
    with Debian trixie and Ubuntu noble).
    The package metadata is constructed from the environment variables
    ELF_PACKAGE_METADATA.
    Setting NO_PKG_METADATA=1 disables the generation of the package metadata.
  * Build target libraries with -mbranch-protection=standard to enable PAC/BTI
    support on arm64 (Emanuele Rocca). Addresses: #1055711.
  * Build target libraries with -fno-omit-frame-pointer, when enabled in
    dpkg-buildflags.
  * Strip again the executables.
