GCC's documentation states that by default lto uses 1 job, it can be optionally overriden with n number of jobs to run in parallel. Pass `-flto=%YJOBS%` when building with GCC LTO to reduce compilation time. Clang does not support this and instead uses thin lto for concurrency. Split LTO flags for GCC and Clang into different variables. Signed-off-by: Joey Riches <josephriches@gmail.com>
