Is there an existing issue for this?

Current Behavior

see https://bugs.gentoo.org/935685

make.defaults syntax is defined in PMS 5.2.4:

The file itself is a line-based key-value format. Each line contains a single VAR="value" entry, where the value must be double quoted.

pkgcheck does not seem to warn on unquoted VAR=value lines, as have been present for a while e.g. in https://github.com/gentoo/gentoo/blob/595c607772111487ab160081434422a98118e566/profiles/features/llvm/make.defaults#L34
