  -----------
  [compiler-rt] Add custom libc++ workaround for CMake < 3.26

The INSTALL_BYPRODUCTS ExternalProject_Add() argument was only added in
CMake 3.26 and the current minimum is 3.20. Work around this by using an
explicit ExternalProject_Add_Step() call for the install step with a
BYPRODUCTS argument. We can't keep using the `install` name here since that
is reserved by the CMake implementation and results in errors when used.

This commit should be reverted once LLVM depends on CMake 3.26.
