    pcr: Remove proguard
    
    The proguard PKGBUILD doesn't provide any source code for proguard,
    and the Aur package it is based on doesn't either.
    
    This is an issue for GPLv2 compliance as well as a practical one:
    we cannot patch the software if we need to.
    
    As for the packages that depend on proguard, the android-sdk
    package depends on it.
    
    However, as far as I know the android-sdk package is a work in
    progress that didn't progress much since 2018. According to the
    commit that added it in pcr-testing:
        commit d424f0813c7bee07cdea2b6863540e1b84abfb0d
    
        addpkg: pcr-testing/android-sdk-meta
    
        Inspired from https://blog.replicant.us/2017/04/there-wont-be-a-replicant-6-0-sdk-because-there-is-already-something-better/
    
        I used the Debian sources since they are fully-free,
        but I still need to add the API level 23 to build an
        app, and then move this to [pcr]
    
    So if someone really wants proguard and/or the android-sdk in
    Parabola, the solution is to make sure that proguard is built
    from source somehow.
    
    In #parabola in liberachat, bill-auger also agreed with me to
    the removal of proguard until a way to build it from source
    is found.
