That forces you to write code that must be initialised at compile time (stored
in the .tdata section if not zeroes), but it's not sufficient for the problem.
To "solve" this problem of initialisation, all accesses to the variable must
see the initialisation. And if the variable is used over multiple TUs, then it
needs to be inline.

Given most code is PIC, I don't see much value in accessing the variable
directly. Make it static in one TU and add an accessor function.
