Cosmocc: still bootstrap 3.9.2 in Makefile

[Vinfall]

I don't know how cosmocc toolchain is supposed to update but

in Makefile

cosmopolitan/Makefile

Lines 151 to 154 in 38930de

	COSMOCC = .cosmocc/3.9.2
	BOOTSTRAP = $(COSMOCC)/bin
	TOOLCHAIN = $(COSMOCC)/bin/$(ARCH)-linux-cosmo-
	DOWNLOAD := $(shell build/download-cosmocc.sh $(COSMOCC) 3.9.2 f4ff13af65fcd309f3f1cfd04275996fb7f72a4897726628a8c9cf732e850193)

and build/objdump

cosmopolitan/build/objdump

Lines 8 to 16 in 38930de

cosmocc is still 3.9.2. Is there a reason it does not match the latest tag (4.0.2)?

The same goes to /pub/cosmos/v/, which does not have pre-compiled binaries for every release.
