That is certainly not the case, look more carefully and you'll note that it
will start compiling tons of sources at once, the problem is just that there is
one
file that takes significantly longer to compile than any other
(asan_interceptors.cc), and with multilib it is compiled 4 times effectively
sequentially (because, libtool always compiles the -fPIC and non-pic
versions one after each other), and multilib variants are also serialized.
