As soon as you customize the uClibc configuration with
uclibc-menuconfig, then we cannot support all the possible build
failures that you will get.
So the solution to this problem is to improve the ARM noMMU support in
Buildroot, making sure that:
1/ The uClibc configuration is automatically adjusted appropriately.
2/ The uClibc tools are not installed.

BR2_BINFMT_FLAT should be set when ARM noMMU is used, because I don't
think ELF binaries are supported on ARM noMMU.
I know Gustavo is working on improving the ARM noMMU, hopefully he will
post patches soon.
