config/optimize, config/functions: refactor lto flags

Browse Source 
Split up the LTO flags in config/optimize and assemble
full C/CXX/LDFLAGS in config/functions.

Add flags for parallel/single-threaded lto and fat/non-fat
lto object creation.

Change the default lto build flag to use non-fat lto objects.
