Subject: [PATCH] sys-libs/libunwind: Install libunwind*.so.* for native ABI
 with USE="split-usr" in /lib instead of /usr/lib.

Block <sys-devel/gcc-config-2.1 which would delete /lib/libunwind.so*.

Port to EAPI="7".
Set correct SLOT="0/8" and block versions of sys-libs/libunwind with old incorrect SLOT="7".
Unconditionally drop *.la files, since *.pc files are installed.

Bug: https://bugs.gentoo.org/667020
