Subject: [PATCH] [libclc] Fix installation w/ ENABLE_RUNTIME_SUBNORMAL

The ARCHIVE artifact kind is not valid for install(FILES ...).

Additionally, install wasn't resolving the target's TARGET_FILE properly
and was trying to find it in the top-level build directory, rather than
in the libclc binary directory. This is because our TARGET_FILE
properties were being set to relative paths. The cmake behaviour they
are trying to mimic - $<TARGET_FILE:$tgt> - provides an absolute path.

As such this patch updates instances where we set the TARGET_FILE
property to return an absolute path.
