[HEADS UP] -Wl,--as-needed is added in rawhide

[Igor Gnatenko]

It's in redhat-rpm-config-118-1.fc30.

If it causes any problems for you - let me know. In the meantime, you can
use `%undefine _ld_as_needed` to disable it.

Thanks for attention!

I still don't see anything to resolve the libtool issue - namely that 
libtool reorders the linker flags in a manner that ends up disabling 
--as-needed. In other words, libtool-using projects (of which there must 
still be plenty) will not benefit from this at all.

See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=347650 for 
details, but in short Debian carries a libtool patch to overcome this 
and others (Gentoo, Mageia at least) have copied that.

At least good projects will benefit from this.

It seems I forgot about this from previous discussions, sorry. I will look
at it and try to work with libtool maintainer to fix it.

Thanks for reminding me about this!

It's important to note that most projects still use some subset of the
autotools framework, so it's not fair to say only "bad" projects use
it.

I don't see any evidence that this was ever fixed in Fedora.  Is that 
right?  What is the best way to get this working on libtool using projects?
