## Message

```
fix linker code writing undefined memory to the output file

missing `extern` on a struct.

but also all these instances that call pwriteAll with a `@ptrCast` are
endianness bugs.

this should be changed to use File.Writer and call writeSliceEndian
instead.

this commit fixes one immediate problem but does not fix everything.

```
