Description

I have a python compiled by pyenv with ccache, and since 72.2.0, setuptools can't link so as expected.

        MAINCC = "ccache /usr/bin/cc"

Expected behavior

it should build so as expected

How to Reproduce

you will need to install pyenv, compile python with https://github.com/pyenv/pyenv-ccache

then use this python to build binary module,

for example

git clone https://github.com/trim21/bencode-py
cd bencode-py
pyenv local 3.10
python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
python setup.py build_ext -i --force

Output

(bencode2) trim21@omv ~/proj/bencode2 $ python setup.py build_ext -i --force -g
running build_ext
building 'bencode2.__bencode' extension
