These lines were introduced in this commit:

What a weird bug. 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?
