What is the exact command you are using?
I tried:

```
rm -rf /home/noah/programs/opensource/glibc-dev/build; mkdir -p
/home/noah/programs/opensource/glibc-dev/build/glibc/; (cd
/home/noah/programs/opensource/glibc-dev/build/glibc/; unset LD_LIBRARY_PAT=
H;
/home/noah/programs/opensource/glibc-dev/src/glibc/configure --prefix=3D/usr
CC=3D"gcc -march=3Dcore2 -Og"; CXX=3D"g++ -march=3Dcore2 -Og"; make -j3 --s=
ilent;);
```

And wasn't able to reproduce this.
