…pp-(major_version)/sycl (intel#22036) Cherry pick of 29ee2a6 Currently, we install all libdevice files to `lib/`. We are trying to improve our packaging to make it easier for Linux distros to package the compiler, and installing dozens of .bc files to `/usr/lib` breaks many distro policies. The main problems are that these files have no use to end users or applications using SYCL, they are only needed by the SYCL compiler itself. Installing to `/usr/lib/libsycl-crt.bc` for example doesn't make sense. This change proposes moving the files to `lib/dpcpp-DPCPP_MAJOR_VERSION/sycl`, so a real example would be `lib/dpcpp-7/sycl`. This change is being made only for Linux, as the file packaging is already much different for Windows, for example today we put libraries in general (such as `libsycl.dll`) in `bin/` but `libdevice` files in `lib`, so I don't see any need to match the behavior between OSes and complicate the Driver code even more. Note the `libdevice` code also generates a host static library, `libsycl-devicelib-host.a`, which is completely untouched by this PR.
