hello:

I got the same on:
arch: mips
gcc:
Using built-in specs.
COLLECT_GCC=/opt/toolchain/rtk-ms-2.0.0-linux-mips-3.18-4.8.5-u0.9.33-toolchain//bin/mips-linux-uclibc-xgcc

cd frr/src/readline-8.0

mkdir build

cd build

../configure --prefix=/home/compile/oem/frr/build/mips-linux --host=mips-linux  CC=mips-linux-gcc CXX=mips-linux-g++ AR=mips-linux-ar STRIP=mips-linux-strip

the running results are as follows:
