gcc-ar is missing LTO plugin

Issue

In Matplotlib, we're running into an issue when using conda-forge compilers that some symbols in compiled extensions are missing.

A straightforward reproducer is to do the following:

$ git clone https://github.com/matplotlib/matplotlib
$ micromamba create -f environment.yml compilers
$ pip install --no-build-isolation --editable .
$ python -c 'import matplotlib'

which ends up failing as:

ImportError: /home/elliott/code/matplotlib/build/cp39/src/_path.cpython-39-x86_64-linux-gnu.so: undefined symbol: _ZN3agg10curve3_div4initEdddddd

This missing symbol (_ZN3agg10curve3_div4initEdddddd = agg::curve3_div::init(double, double, double, double, double, double)) is part of a static library that is built into the extension shared library, except it disappeared with the conda-forge compilers. If you build the library with verbose settings (by passing --config-settings=compile-args=-v -v to pip), then you can find a warning somewhere in there that points to gcc-ar plugins:
