I have pretty strong feelings that we shouldn't be using remove like
this, or duplicating data. Its susceptible to breakage when one value
changes and the other does not. Can you rework this so it doesn't use
remove, or duplicate data?

In case its not clear, you can do something like:

CODEGEN_PYTHON_RDEPENDS = "python3 python3-distutils python3-xml"
CODEGEN_PYTHON_RDEPENDS_mingw32 = ""

RDEPENDS_${PN}-codegen += "${CODEGEN_PYTHON_RDEPENDS}"

which is much more maintainable.

Cheers,

Richard
