Subject: [PATCH] darwin.architecture: correctly install headers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I’m not going to fix all of them but this is the best way to do this
in Apple things. Just add ‘EXPORT_DSTDIR’ to the installFlags & set
‘DSTDIR’ to $(out). Please do this instead of the patching!
