+mold: update to 2.31.0
+
+Packaging changes:
+- removed CMakeLists patch as it is no longer necessary
+
+Upstream changes:
+2.30.0 -> 2.30.1:
+New Features:
+- Up to 10% faster when linking very large, debug info-enabled
+  executables
+- `-z start-stop-visibility=hidden` is now supported so that
+  linker-synthesized __start_<section-name> and
+  __stop_<section-name> symbols can be completely hidden from other
+  ELF modules.
+- -Bsymbolic-non-weak and -Bsymbolic-non-weak-functions options
+  are now supported for compatibility with LLVM lld. Just like lld,
+  these options control which symbols are exported as dynamic
+  symbols. -Bsymbolic-non-weak makes the linker to export only weak
+  symbols, whereas -Bsymbolic-non-weak-functions makes it to export
+  only weak function symbols.
+Bug Fixes:
+- if a linker script contains a newline character in the beginning
+  four bytes of a file, it was not recognized as a linker script.
+- the INPUT linker script command may have found a different file
+  than GNU ld would
+- Fixed the --repro option from produced corrupted tar files
+
+https://github.com/rui314/mold/releases/tag/v2.30.1
+
+2.4.1 -> 2.30.0:
+Housekeeping:
+- Version change to avoid GNU libtool from mistaking mold 2.4.1 for
+  GNU ld 2.4.1
+- Sections with unknown section types are now reported as errors.
+Bug Fixes:
+- Fixed having inserted an unnecessary gap before the .bss section in
+  an output file, thereby creating an extra segment for it.
+- Fixed failing with the "ConcurrentMap is full" error message if
+  --gdb-index was used.
+- Suppressed warnings for generating an excessive number of
+  "ignoring .llvm_addrsig section without sh_link".
+
+https://github.com/rui314/mold/releases/tag/v2.30.0
+
+2.4.0 -> 2.4.1:
+Bug Fixes:
+- Fixed promoting weak dynamic symbols to strong ones under a rare
+  circumstance, which caused "undefined symbol" error at runtime.
+- If two or more VERSION clauses in a version script match to the
+  same symbol, the first one took precedence. This was incompatible
+  with GNU ld, which gives the last one the highest priority,
+  causing a Qt library link failure
+- By default, we demangle symbols in error messages so that they are
+  easier to read. Previously, Rust symbols could accidentally be
+  demangled as C++ symbols. Now, mold attempts to demangle symbols as
+  Rust ones only for object files created by rustc
+
+https://github.com/rui314/mold/releases/tag/v2.4.1
+
+2.3.3 -> 2.4.0:
+New Features:
+- added the --spare-program-headers=<number> option
+- `-z rewrite-endbr` option rewrites superflous endbr64 instructions
+  with nop as a countermeasure against control-flow highjacking
+  attacks.
+
+Bug Fixes:
+- Fixed not handling object files containing multiple .eh_frame
+  sections
+- `mold -run <command>` is an easy way to run the given command with
+  a virtual environment in which the ld command is replaced with
+  mold.
+- Fixed the production of non-working executables on a rare occasion
+  when all thread-local variables lacked an initial value and the
+  read-only data required alignment equal to or greater than the page
+  size.
+- Fixed possible assignment to a different symbol version to a symbol
+- Recent versions of LLVM emit a machine code sequence for TLSDESC
+  thread-local variables that would be mis-optimized.

+mold is a new linker that is optimized for modern multi-core machines.
+
+mold is command-line compatible with the other major linkers, GNU ld, GNU gold
+and LLVM lld, yet it is several times faster than them. Its goal is to increase
+programmer productivity by speeding up program build time, especially for rapid
+edit-build-test-debug cycles.
