With dpkg-dev 1.17.6, there's a new symbols file field named
Ignore-Blacklist-Groups that can be used by the toolchain packages to
ignore the entire blacklist group for the aeabi symbols, which are now
blacklisted by regex instead of by an explicit list. This means that
dpkg-dev will automatically blacklist new introduced symbols w/o
having them leak into other package symbol files or having them FTBFS,
and needing to add them manually to dpkg-dev and libgcc1.symbols.aeabi.

But to make gcc unconditionally include unknown aeabi symbols the
ignore-blacklist tag is not enough, instead the new field can be used
which disables the entire regex for that group. Adding something like:

,---
* Ignore-Blacklist-Groups: aeabi
`---

at the top of libgcc1.symbols.aeabi should do the trick. You can then
remove the ignore-blacklist tag if you want, or I guess you could keep
it to avoid having to Build-Depend on a newer dpkg-dev.

Thanks,
Guillem

Control: retitle -1 libgcc1: Can switch to use new Allow-Internal-Symbol-Groups for aeabi symbols

I've deprecated the Ignore-Blacklist-Groups in dpkg 1.20.1, and
Allow-Internal-Symbol-Groups should be used instead.

Thanks,
Guillem
