OK, '--enable-plugins' did work. As a sidenote, just what is it with multislot useflag, that it make packages complain: * QA Notice: Expected SLOT='0', got 'i686-pc-linux-gnu-2.20' IIRC, it actually breaks something with gcc ebuild (fix_libtool_files phase, I think). And should it prepend CHOST ?
*** Bug 289869 has been marked as a duplicate of this bug. ***
As I said, bug 289869 suggests it's not '--as-needed' only problem.
I have this problem as well, amd64 with "--as-needed" enabled. If further information is needed, then please ask.
I don't think --as-needed is the culprit here. I don't use that flag and still get the same build errors: libtool: link: i686-pc-linux-gnu-gcc -W -Wall -Wstrict-prototypes -Wmissing-prototypes -march=pentium4 -O2 -pipe -Wl,-O1 -o .libs/ld-new

Same here, with "multitarget nls -gold -multislot -test -vanilla". 2.19.1-r1 compiles successfully.
summary is misleading - it not builds with any LDFLAGS, the only thing helped me is adding '--enable-plugins' into configuration phase
(In reply to comment #7) > summary is misleading - it not builds with any LDFLAGS, the only thing helped > me is adding '--enable-plugins' into configuration phase > Of course, it is. When I opened this bug, I was not sure, if '--as-needed' is the reason of this bug. Since then, that mailing list discussion proves, it's not.
I came across this while upgrading my system, so in case it is a common problem it may be worth mentioning how to easily add "--enable-plugins", so that the package installs. I used: # EXTRA_ECONF="--enable-plugins" emerge binutils
I got this bug with "multitarget" only.

added the fix merged upstream
