commit 0b6e22e160e18201fd5308cf2e1c558a031fb124

    configure: Use SOURCE_DATE_EPOCH environment variable
    
    This package defines PKGBLDDATE as build timestamp which makes
    it non reproducible. Use SOURCE_DATE_EPOCH if it is found, otherwise
    use build timestamp.
    Yocto needs this for reproducibility.
