The predefined macros are not referring to product family names, but to the underlying architecture. See

https://wiki.ubuntu.com/ARM/Thumb2PortingHowto
http://en.wikipedia.org/wiki/List_of_ARM_microprocessor_cores

IMHO, this is the only interesting information for code separation. However, the majority of Nut/OS users seems to prefer the popular product names. See the thread that started about one year ago

http://www.digipedia.pl/usenet/thread/13045/12384/

I never liked this decision and Ole recently followed my view (his post from Oct. 23rd). There had been no protests so far, so we should move from __CORTEX__ to GCC's build-in macros. Note, that ARMv7 does have several variants and also many things in common. But as far as I can say, __ARM_ARCH_7M__ is the only architecture that's currently supported by Nut/OS for the Cortex family.
