-Subject: [PATCH] Assume non-git LLVM is fresh if the stamp file exists
-
-Rustbuild usually writes the LLVM submodule commit in a stamp file, so
-we can avoid rebuilding it unnecessarily. However, for builds from a
-source tarball (non-git), we were assuming a rebuild is always needed.
-This can cause a lot of extra work if any environment like `CFLAGS`
-changed between steps like build and install, which are often separate
-in distro builds.
-
-Now we also write an empty stamp file if the git commit is unknown, and
-its presence is trusted to indicate that no rebuild is needed. An info
-message reports that this is happening, along with the stamp file path
-that can be deleted to force a rebuild anyway.

+Description: Set DT_SONAME when building dylibs
+ In Rust, library filenames include a version-specific hash to help
+ the run-time linker find the correct version.  Unlike in C/C++, the
+ compiler looks for all libraries matching a glob that ignores the
+ hash and reads embedded metadata to work out versions, etc.
+ .
+ The upshot is that there is no need for the usual "libfoo.so ->
+ libfoo-1.2.3.so" symlink common with C/C++ when building with Rust,
+ and no need to communicate an alternate filename to use at run-time
+ vs compile time.  If linking to a Rust dylib from C/C++ however, a
+ "libfoo.so -> libfoo-$hash.so" symlink may well be useful and in
+ this case DT_SONAME=libfoo-$hash.so would be required.  More
+ mundanely, various tools (eg: dpkg-shlibdeps) complain if they don't
+ find DT_SONAME on shared libraries in public directories.
+ .
+ This patch passes -Wl,-soname=$outfile when building dylibs (and
+ using a GNU linker).
