-# Patch needed to support cross compilation for arm64 on amd64 for node 16 and 18.
-# The PR introducing the issue (https://github.com/nodejs/node/pull/43200) was merged in main released in v20 and backported to v18 (https://github.com/nodejs/node/pull/44353) and v16 (https://github.com/nodejs/node/pull/44886)

-# Therefore the fix needs to be re-applied to v16 and v18 if we want to compile those too.
-# the initial patch works on v18, for v16 a reroll was required.
