Code Review

This pull request removes a duplicate lto configuration from the faiss package's xmake file. While removing the redundant configuration is a good step, the change is incomplete because the usage of this configuration remains in the install script. This could lead to potential build conflicts with xmake's native LTO handling. I have added a comment to highlight this issue and suggest a more complete fix.
