GCC does have link-time optimisation.
CFLAGS += -flto
CXXFLAGS += -flto
LDFLAGS += -flto

The only drawback is that object files will get bigger and linking the
test programs will take significantly longer. But since the performance
overhead of actual LTP code is mostly trivial compared to time spent in
system calls and waiting for I/O operations, I don't think we'll gain
anything by turning these optimizations on.
