Adjust linker arguments for LTO parallelization
GCC 10+ and Clang 4+ support controlling the number of LTO threads/jobs used
during linking. Use the build2 scheduler to allocate up to the number of
hardware threads to the GCC or Clang linker processes when -flto=auto or
-flto=thin is specified, respectively. Otherwise, GCC or Clang will attempt to
spawn the number of hardware threads detected for each linker process, which
could result in up to n^2 linker threads on a CPU with n hardware threads.
