Environment: Fix passing envrionment variables CPPFLAGS and CFLAGS Or other language flags that use CPPFLAGS (like CXXFLAGS). The problem here is actually rather simple, `dict.setdefault()` doesn't work like I thought it did, I thought it created a weak entry, but it actually is equivalent to: ```python if k not in dict: dict[k] = v ``` Instead we'll use an intermediate dictionary (a default dictionary actually, since that makes things a little cleaner) and then add the keys from that dict to self.options as applicable.
