Building libfuzzer-based fuzzers for android currently does not work.

Gn args (minimized):
target_os = "android"
use_libfuzzer = true

This gives gn errors for a lot of targets:

===========================================================================
$ gn gen out/tmp

If I just remove all "fuzzer_test"s which cause these problem, I can generate the build files, but the target I want to compile is not there:

===========================================================================
$ ninja -C out/tmp v8_wasm_compile_fuzzer
ninja: Entering directory `out/tmp'
ninja: error: unknown target 'v8_wasm_compile_fuzzer', did you mean 'v8:wasm_compile_fuzzer'?
===========================================================================

Any gn expert who can help on this?
