[Clfs-dev] Why No MMU/No ARM Iinstruction Set Architectures mentioned in [4.3. Build Variables ].

[Israr Sayed]

As far as Cortex-R and Cortex-M are concerned , they are MMU less devices.
They are not having ARM Instruction Set.Whereas Libgcc , expects both.
Those Devices should not be build for OS based GCC build. If somehow they got build, they wont be working.
It is kind of misleading.They should be mentioned seperately for Bare Metal and Linux based configure. 
I have discussed this in GCC ML.https://gcc.gnu.org/ml/gcc-help/2019-11/msg00026.html.
