1. Roland suggestion is orthogonal to mine.
2. Roland suggestion may not be easy to implement safely.
3. Even if it works, use it in a test script to cover all cases is complex.
4. We can enable --enable-test-multi-arch by default and change
"make install" to remove libc-test.o from libc.a and libc-test.os from
libc.so when installing libc.
Again, this only covers the testing part, not the granting user control
part, which is a separate issue.
