tryout to get cross compilation to work.

currently hitting a hiccup building rusty_v8, which has been documented here and worked around there

=> => # error: failed to add native library /app/target/aarch64-unknown-linux-musl/release/gn_out/o
=> => # bj/librusty_v8.a: file too small to be an archive                                          
=> => # error: could not compile `v8` due to previous error                                        
=> => # warning: build failed, waiting for other jobs to finish...

Was able to solve the rusty_v8 bit by targeting gnu instead of musl whilst still remaining on aarch64! Took way too long to figure that out, though 😭 -- and doesn't seem like there's much appetite at deno_land to finally support musl

Saw there was some discussion re: getting rid of this dependency in the router repo. After this, would love to see that happen, lol.
