Yes, I've done that when I realized my ARM development box setup
missed several Debian packages building sandbox (I only build Linux
kernels and U-Boot boards natively on ARM). However, after installing
all those packages it is still not possible to build a sandbox on ARM.
So currently I am switching to cross compiling on my Intel laptop.
Later, I'll come back to the ARM box to see whether we need some
documentation update for doc/build/gcc.rst.

Thanks,
Tony
