xxhash: WIP

[extrowerk]

The makefile checks for uname here: https://github.com/Cyan4973/xxHash/blob/dev/Makefile#L572
and then it tries to use ginstall, which is not available on my side.
I belive there must be an easier way than patching it, but I have failed to find it.

This is what I use to build from source:

                sudo pkg install gcc14 git pkg-config python-313 gnu-make gnu-coreutils
                # install libxxhash from source
                git clone --depth 1 https://github.com/Cyan4973/xxHash.git
                cd xxHash
                sudo gmake install INSTALL=/usr/gnu/bin/install PREFIX=/usr/local
                cd ..
                export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig:${PKG_CONFIG_PATH:-}"
                export LD_LIBRARY_PATH="/usr/local/lib:${LD_LIBRARY_PATH:-}"
