From a295ac1d44142a07157ece63a78493bbf9eb6ef6 Mon Sep 17 00:00:00 2001 From: Stefan Reinauer Date: Thu, 8 Feb 2024 21:18:05 -0800 Subject: crossgcc: Add buildgcc support for Apple M1/M2 devices GMP and IASL don't compile with the default compiler and linker flags: - GMP's check for the MacOS architecture hard coded x86_64 but it also needs to know about arm64. - iasl does some trickery on pointer alignment to save space(?), so we need to tell clang about it.
