Comment 1 by manojgupta@chromium.org, Dec 20

Chirantan, can you restrict the fuzzer to be included with asan + fuzzer builds?

Probably modifying the RDEPEND in chromium-os-fuzzers ebuild to include p9 only when asan USE is set will work.

chromium-os-fuzzers: Only build rust fuzzers under asan

There is no ubsan in rust and msan triggers a crash in the standard
library so for now only build rust fuzzers when we are using asan.
