+ support for -CLflto_nosystem option to perform LTO for everything except
for the system unit, as there are several bugs in the Xcode linkers
that trigger when the system unit is involved:
o Xcode 9.3: the second symbol associated with routines that have multiple
symbols (such as FPC_INTERLOCKED*) gets moved to the next routine (so
e.g. calling InterlockedIncrement results in calling InterlockedExchange)
o Xcode 10.1: the linker does not generate native code for the personality
routine (probably because it's not referenced directly anywhere)
