Bug in CubeMX generating Makefile, missing some CPU info.

[Bertha]

I did not tested if this is specific to all MCU but for U5 familly this is sure:

How to reproduce :

Launch cubeMX, (6.7.0)

select U5 board like nucleo

Go to project manager, and select under Toolchain - Makefile.

--> Bug, the Makefile genereted is missing some details on CPU, so cannot build.

To solve it add :

CPU = -mcpu=cortex-m33

after

#######################################
# CFLAGS
#######################################
# cpu

Moreover, and i am not sure about this but I think I read somewhere that U5 was using : fpv5-sp-d16 and not fpv4-sp-d16 as in generated makefile

so I replaced

FPU = -mfpu=fpv4-sp-d16

by this :

FPU = -mfpu=fpv5-sp-d16

Please review the makefile generation under cudeMX seems to have some mistake for U5 series at least.

Hope this help and avoid other to lose time to spot this.
