Ayke van Laethem 66d8899aa7 main: set the current working directory when calling an external linker
In particular, while LLVM lld supports -L for linker scripts imported
with the `INCLUDE` command, GNU ld does not seem to support this.

This is a prerequisite for supporting the HiFive1 board in the TinyGo
Playground.
