Please get users/hjl/pr26314/test branch at

https://gitlab.com/x86-binutils/binutils-gdb/-/tree/users/hjl/pr26314/test

and build binutils with GCC 10:

CC="/usr/gcc-10.1.1-x32/bin/gcc -flto -ffat-lto-objects -Wl,--as-needed
-fcf-protection" CXX="/usr/gcc-10.1.1-x32/bin/g++ -flto -ffat-lto-objects
-Wl,--as-needed -fcf-protection"
/export/gnu/import/git/gitlab/x86-binutils/configure \
        --enable-shared \
         \
        --enable-plugins --disable-gdb --disable-gdbserver
--disable-libdecnumber --disable-readline --disable-sim --with-sysroot=/
--with-system-zlib \
        --prefix=/usr/local \
        --with-local-prefix=/usr/local

I got

[hjl@gnu-cfl-2 build-x86_64-linux]$ nm -D binutils/.libs/ar | grep lrealpath
0000000000000000 A lrealpath
[hjl@gnu-cfl-2 build-x86_64-linux]$
