-march v5 is invalid for GCC 9.2.1. ARM11 is an armv6 implementation. So
change the architecture flag for the compiler to armv6.

After I read up on it I would add something to the commit saying
that the first -march=armv5 must have been wrong all the time
since there are no known implementations of
armv5, only armv5t, armv5te and armv5tej. Maybe add a link
to this:
