You don't need MCU_STM32F411xE. STM32F411xE is the define you need to look for!
It is what we already use to include the vendor header.

Did you run with a custom config?

Running conf/nucleo_f401re with 6450 gives following defines in
#define CM3_GCC
#define MCU_STM32F401xE
#define MCU_CM3 1
#define MCU_STM32 1
#define MCU_STM32F4 1
#define MCU_STM32F401 1
#define STM32F401xE 1

So here neither MCU_STM32F401 is missing nor some define for the exact part.
But MCU_STM32F401xE could be ommited. I will clean up as I find time...

Please recheck!
