 # Preprocessing steps work as follows:
 #
 # 1. Apply our patches to the extracted source. See each patch for more info.
 #
 # 2. Create a macOS-Clang-Linux mkspec using our mac-qmake.conf.
 #
 # 3. After making a copy of the mkspec for the linux-arm-gnueabi host, named
-# bitcoin-linux-g++, replace instances of linux-arm-gnueabi with $(host). This
-# way we can generically support hosts like riscv64-linux-gnu, which Qt doesn't
-# ship a mkspec for. See it's usage in config_opts_* above.
+#    bitcoin-linux-g++, replace tool names with $($($(package)_type)_TOOL).
 #
 # 4. Put our C, CXX and LD FLAGS into gcc-base.conf. Only used for non-host builds.
 #
-# 5. Do similar for the win32-g++ mkspec.
-#
-# 6. In clang.conf, swap out clang & clang++, for our compiler + flags. See #17466.
-#
-# 7. Adjust a regex in toolchain.prf, to accomodate Guix's usage of
-# CROSS_LIBRARY_PATH. See core#15277.
+# 5. In clang.conf, swap out clang & clang++, for our compiler + flags. See #17466.
