Can I get rid of LTO information from a LIB?

[PcX <xunxun1982@xxxxxxxxx>]

Hi, all

    If I use "-flto" to build one library, the library usually becomes 
very large.
    Now I want to remove the lto information to release it, but don't 
want to rebuild the lib.
    How can I do this?

    Thanks.
