runtime: fix external address declarations

Browse Source 
This is the same problem as in
https://github.com/tinygo-org/tinygo/pull/605, but other targets also
suffer from it.

Discovered with the GBA target, but as pointed out in
https://bugs.llvm.org/show_bug.cgi?id=42881#c1 this appears to be a bug
in the way external globals are declared, not in LLVM. Therefore I
decided that fixing it everywhere would be the best thing to do.
