Hi,
I want to develop rumpkernel application on baremetal arm platform.
I tried to compile rumpkernel as following steps:
$ export CC=arm-none-eabi-gcc
$ export CXX=arm-none-eabi-g++
$ ./build-rr.sh baremetal -- -F ACLFLAGS=-march=armv7-a
But this was failed:
...

I also tried to compile frankenlibc.
But it also failed:
$ ./build.sh qemu-arm

I think arm-rumprun-netbsdelf-eabi-cc needs "-nostdlib" option.
Could you tell me how to fix them?
