I'm reproducing the problem with libfuse.so ; in my case it broke sys-boot/grub's configure process but the missing __fuse_read_cmd symbol in libfuse.so is the same issue. Also fixed on my end when disabling LTO for sys-fs/fuse.
I'd like to provide a link my related issue on the gentooLTO overlay, as we've done some digging on the absence of the __fuse_read_cmd symbol in libfuse.so when compiled with LTO under GCC 8.2.0. No final conclusions, but I think the discussion can be useful for anyone attempting to debug this. https://github.com/InBetweenNames/gentooLTO/issues/139

The straightforward way to trigger the failure is to build fuse with -Wl,--no-undefined: CFLAGS="-O2 -flto" CXXFLAGS="-O2 -flto" LDFLAGS="-O2 -flto -Wl,--no-undefined" build fuse-2.9.9.ebuild clean compile /bin/sh ../libtool --tag=CC --mode=link x86_64-pc-linux-gnu-gcc -O2 -flto -pthread -ldl -version-number 2:9:9 -Wl,--version-script,./fuse_versionscript -O2 -flto -Wl,--no-undefined -o libfuse.la -rpath /usr/lib64 fuse.lo fuse_kern_chan.lo fuse_loop.lo fuse_loop_mt.lo fuse_lowlevel.lo fuse_mt.lo fuse_opt.lo fuse_session.lo fuse_signals.lo buffer.lo cuse_lowlevel.lo helper.lo modules/subdir.lo modules/iconv.lo mount.lo mount_util.lo libtool: link: x86_64-pc-linux-gnu-gcc -shared -fPIC -DPIC .libs/fuse.o .libs/fuse_kern_chan.o .libs/fuse_loop.o .libs/fuse_loop_mt.o .libs/fuse_lowlevel.o .libs/fuse_mt.o .libs/fuse_opt.o .libs/fuse_session.o .libs/fuse_signals.o .libs/buffer.o .libs/cuse_lowlevel.o .libs/helper.o modules/.libs/subdir.o modules/.libs/iconv.o .libs/mount.o .libs/mount_util.o -ldl -O2 -flto -pthread -Wl,--version-script -Wl,./fuse_versionscript -O2 -flto -Wl,--no-undefined -pthread -Wl,-soname -Wl,libfuse.so.2 -o .libs/libfuse.so.2.9.9 libtool: link: (cd ".libs" && rm -f "libulockmgr.so.1" && ln -s "libulockmgr.so.1.0.1" "libulockmgr.so.1") libtool: link: (cd ".libs" && rm -f "libulockmgr.so" && ln -s "libulockmgr.so.1.0.1" "libulockmgr.so") libtool: link: ( cd ".libs" && rm -f "libulockmgr.la" && ln -s "../libulockmgr.la" "libulockmgr.la" ) /usr/lib/gcc/x86_64-pc-linux-gnu/9.1.0/../../../../x86_64-pc-linux-gnu/bin/ld: /tmp/portage/sys-fs/fuse-2.9.9/temp/libfuse.so.2.9.9.HGIMtu.ltrans0.ltrans.o: in function `mt_chan_receive': <artificial>:(.text+0xdafe): undefined reference to `__fuse_read_cmd@'
I think it's a bug in LTO partition code in gcc/binutils. It does not understand .symver directives.

That causes linker failures in form of: <artificial>:(.text+0xdafe): undefined reference to `__fuse_read_cmd@' To work it around we filter out -flto flags (already done for masked ebuilds).
