You don't need any of these flags if you are building mpich on an armv7 platform. Just do ./configure.

Hello
Sorry if I am being so noob in asking this.
I want to build mpich for armv7 and in doing so, I want to specify arm related flags specifically, CFLAGS="-O2 –march=armv7-a –mtune=cortex-a8 –mfpu=neon –mfloat-abi=hard –fomit-frame-pointer"
But when I configure mpich and specify CFLAGS it fails to start by throwing this error.

Any help?
Thanks
