GCC's documentation states that by default lto uses 1 job, it can be optionally overridden
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.
