rustc: Fix permission denied error in 'ar' when lto is enabled
The reason that 'ar' can fail with permission denied is that when link-time optimizations are enabled, rustc copies libraries into a temporary directory, preserving file permissions, and subsequently modifies them using 'ar'. The modification can fail because some package managers may install libraries in system directories as read-only files, which means the temporary file also becomes read-only when it is copied. I have fixed this by giving the temporary file's owner read+write permissions after the copy. I have also added a regression test for this issue.
