I am not a developer of associated with rpm....

Just a user.

I don't do that

rpm -E %_lib
lib

rpm -E %_libdir
/usr/lib

I build a scratch built os's for raspberry pi 
armv7l-unknown-linux-gnueabihf and aarch64-unknown-linux-gnu

I have not seen this error on any of my builds

rpm --version
RPM version 4.18.0

%files -f %{_builddir}/filelist.rpm
%defattr(-,root,root)

 From working system.....

ls -hal usr/lib/crt*

add this to .rpmmacro in the user home directory where you are building

It turns off build ides

%_unique_build_ids 0
%_build_id_links none

from my spec file:

%prep
%setup -q -n elfutils-%{version}
# remove failing test due to missing glibc debug package
sed -e 's/run-backtrace-native.sh//g' -i tests/Makefile.am
autoreconf -fiv

%build
_options=(--prefix=/usr
     --sysconfdir=/etc
     --program-prefix=eu-
     --enable-deterministic-archives
     --disable-debuginfod
     --disable-libdebuginfod)
./configure "${_options[@]}"
%{make_build}

%install
%{make_install}
