Something like:

 % ~/glibc/configure --prefix=/usr --libdir=/usr/lib --libexecdir=/usr/lib --with-headers=/usr/include --enable-add-ons --enable-kernel=4.10 --with-tls --with-__thread --enable-bind-now --without-gd --without-cvs --disable-profile --disable-multi-arch --disable-werror 
 % make -j128
 % make -j128 check

But I've attached the testcase, so building should be unnecessary.
