For

https://github.com/davidmalcolm/rhbz-1543912

with binutils master branch, I got

mkdir build
gcc -I ./src -flto -O2 -g -c src/bootchart.c -o build/bootchart.o
gcc -I ./src -flto -O2 -g -c src/log.c -o build/log.o
gcc -flto -g -Wl,--gc-sections -Wl,--print-gc-sections \
  build/bootchart.o build/log.o \
          -o build/systemd-bootchart
/usr/local/bin/ld: removing unused section '.rodata.cst4' in file
'/usr/lib/gcc/x86_64-redhat-linux/7/../../../../lib64/crt1.o'
/usr/local/bin/ld: removing unused section '.data' in file
'/usr/lib/gcc/x86_64-redhat-linux/7/../../../../lib64/crt1.o'
/usr/local/bin/ld: removing unused section '.rodata' in file
'/usr/lib/gcc/x86_64-redhat-linux/7/crtbegin.o'
/usr/lib/rpm/debugedit build/systemd-bootchart

It looks normal to me.
