See tracker bug.
Well glibc is a bit of a special case since it needs to do "manual" stripping (and the ebuild accordingly declares RESTRICT=strip). We will need to copy / adopt the logic somehow.
Let's fix this a while after EAPI=7 can be used in the stable tree. Depends on "dostrip".
Ping.

Can someone handle this now? It's passed the Jun 2019 date limit. I'd like to be able to drop more portage-specific hacks from pkgcore/pkgcheck.

This change effectively brings back bug #46186. To reproduce the problem, make sure you don't have nostrip or splitdebug features enabled, and reinstall glibc. When using gdb to debug a multithreaded program, it will complain: warning: Unable to find libthread_db matching inferior's thread library, thread debugging will not be available. the issue can be traced back to libpthread.so being stripped. A little more background on this issue: The real problem is not that gdb relies on debug info in libpthread.so, on the contrary, gdb doesn't care. It's *glibc* libthread_db that requires a local symbol (nptl_version) in libpthread.so to verify that their versions match. (See https://sourceware.org/gdb/wiki/FAQ#GDB_does_not_see_any_threads_besides_the_one_in_which_crash_occurred.3B_or_SIGTRAP_kills_my_program_when_I_set_a_breakpoint for the official explanation.) Should we revert this change or reopen bug #46186? Thanks.

Please file a new bug with steps to reproduce and 'emerge --info' details. It was working for me on amd64.

See https://bugs.gentoo.org/697910 for details and reproducer. Also see ebuild note that explains indirect mechanics of how glibc relies on gdb's ability to traverse local symbols. In EAPI=7 ebuilds (glibc-9999) we do selective stripping.
