This looks like the MariaDB compilation uses gcc-ar instead of binutils ar. Based on what I can tell from the code, gcc-ar here expects to be in a non-standard path and named "ar" in order to wrap the binutils ar, similar to how ccache works. But gcc-ar is named "gcc-ar" and located in the same dir as the binutils ar, so things break. Is MariaDB using LTO?
