Currently armv6 is an experimentally supported target. One of the issues folks will run into is
that we currently detect

pi@espresso:~/julia $ make print-BB_TRIPLET_LIBGFORTRAN_CXXABI
BB_TRIPLET_LIBGFORTRAN_CXXABI=armv7l-linux-gnueabihf-libgfortran5-cxx11

This is on my Rasberry Pi Zero W.

The issue is that:

pi@espresso:~/julia $ gcc -dumpmachine
arm-linux-gnueabihf

doesn't differentiate between ARMv6 or ARMv7.

pi@espresso:~/julia $ uname -m
armv6l
