Some old versions of `rustc` did not report the LLVM version without
the patch version, e.g.:
$ rustc --version --verbose
rustc 1.48.0 (7eac88abb 2020-11-16)
binary: rustc
commit-hash: 7eac88abb2e57e752f3302f02be5f3ce3d7adfb4
commit-date: 2020-11-16
host: x86_64-unknown-linux-gnu
release: 1.48.0
LLVM version: 11.0
Which would make the new `scripts/rustc-llvm-version.sh` fail and,
in turn, the build:
$ make LLVM=1
SYNC include/config/auto.conf.cmd
./scripts/rustc-llvm-version.sh: 13: arithmetic expression: expecting primary: "10000 * 10 + 100 * 0 + "
init/Kconfig:83: syntax error
init/Kconfig:83: invalid statement
make[3]: *** [scripts/kconfig/Makefile:85: syncconfig] Error 1
make[2]: *** [Makefile:679: syncconfig] Error 2
make[1]: *** [/home/cam/linux/Makefile:780: include/config/auto.conf.cmd] Error 2
make: *** [Makefile:224: __sub-make] Error 2
Since we do not need to support such binaries, we can avoid adding logic
for computing `rustc`'s LLVM version for those old binaries.
Thus, instead, just make the match stricter.
Other `rustc` binaries (even newer) did not report the LLVM version at
all, but that was fine, since it would not match "LLVM", e.g.:
$ rustc --version --verbose
rustc 1.49.0 (e1884a8e3 2020-12-29)
binary: rustc
commit-hash: e1884a8e3c3e813aada8254edfa120e85bf5ffca
commit-date: 2020-12-29
host: x86_64-unknown-linux-gnu
release: 1.49.0

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
