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).
Our patch to mdbook installs symlinks to systems versions of font-awesome,
highlight, etc. Upstream mdbook otherwise doesn't use symlinks, so this
doesn't affect anything else that's already generated.

[PATCH] Allow using external builds of the compiler-rt profile lib
This changes the bootstrap config `target.*.profiler` from a plain bool
to also allow a string, which will be used as a path to the pre-built
profiling runtime for that target. Then `profiler_builtins/build.rs`
reads that in a `LLVM_PROFILER_RT_LIB` environment variable.
explicitly disable split unpacked debuginfo for now on riscv64,
it's broken and we don't want cargo to auto-enable it..

Gbp-Pq: Name u-riscv-disable-unpacked-split-debuginfo.patch
When cfg(test), Config::parse doesn't parse a config.toml but uses default
values, failing when the initial rustc is needed. This is a workaround before
upstream issue gets solved.
