Sorry being unclear here, trying being clearer with an example:
I have a /data/Docs on my linux box, which is handled by git

I export /data/Docs via SAMBA, and use the Finder under Mac OS to have it
mounted on my Mac OS X box:
//tb@Linux/Docs on /Volumes/Docs (smbfs, nodev, nosuid, mounted by tb)

In the above example
/data/Docs/.git/config was created by Linux, so it does not have
core.precomposeunicode set, neither false nor true.
The Linux box does not have  UTF-8-MAC under iconv,
but will ignore core.precomposeunicode anyway (since the code is not compiled 

The Mac OS machine sees it under /Volumes/Docs/.git/config
And here we want the precomposition, even if core.precomposeunicode
is not present in the config.
