After spending hours looking at the generated assembly output, it seems
the problem is NOT with the compiler, but with the linker. Basically,
for XIP code, only the first function in the assembly output is
executed. With -funit-at-a-time, that was usually the function placed
last in the code. So I'm now chasing a bug either in our linker commands
or in binutils.
