-# We have some triples which are bootstrapped from other triples, and this means
-# that we need to fixup some of the native tools that a triple depends on.
-#
-# For example, MSVC requires the llvm-ar.exe executable to manage archives, but
-# it bootstraps from the GNU Windows triple. This means that the compiler will
-# add this directory to PATH when executing new processes:
-#
-# $SYSROOT/rustlib/x86_64-pc-windows-gnu/bin
-#
-# Unfortunately, however, the GNU triple is not known about in stage0, so the
-# tools are actually located in:
-#
-# $SYSROOT/rustlib/x86_64-pc-windows-msvc/bin
-#
-# To remedy this problem, the rules below copy all native tool dependencies into
-# the bootstrap triple's location in stage 0 so the bootstrap compiler can find
-# the right sets of tools. Later stages (1+) will have the right host triple for
-# the compiler, so there's no need to worry there.
