Hi @mgorny and @krytarowski! This is my best effort fixing build errors caused by D73816 <https://reviews.llvm.org/D73816>. I don't have a good way to build and test it on NetBSD and would need your help with this.


`sigaltstack` interception is implemented D73816 <https://reviews.llvm.org/D73816>. This updated NetBSD bits to fix the build errors.
