libcxx: Set CMAKE_BUILD_WITH_INSTALL_RPATH

cmake 3.22+ is causing install failures e.g.

| -- Install configuration: "Debug"
| -- Installing: /mnt/b/yoe/master/build/tmp/work/armv7at2hf-neon-yoe-linux-gnueabi/libcxx/13.0.1-r0/image/usr/lib/libc++.so.1.0
| -- Installing: /mnt/b/yoe/master/build/tmp/work/armv7at2hf-neon-yoe-linux-gnueabi/libcxx/13.0.1-r0/image/usr/lib/libc++.so.1
| -- Set runtime path of "/mnt/b/yoe/master/build/tmp/work/armv7at2hf-neon-yoe-linux-gnueabi/libcxx/13.0.1-r0/image/usr/lib/libc++.so.1.0" to ""
| -- Installing: /mnt/b/yoe/master/build/tmp/work/armv7at2hf-neon-yoe-linux-gnueabi/libcxx/13.0.1-r0/image/usr/lib/libc++.so
| CMake Error at cmake_install.cmake:88 (file):

Apply a workaround by building install time rpaths directly during build time
too.

Real fix perhaps will be in cmake somewhere.
