I ninja microdump_stackwalk but I get dump_syms instead:

This is my gn config:
is_component_build = false
is_debug = false
dcheck_always_on = true
use_goma = true
goma_dir = "/usr/local/google/home/primiano/tools/goma"
enable_nacl = false
target_os = "android"

The ./obj/breakpad/microdump_stackwalk.ninja is clearly wrong:
rule __breakpad_microdump_stackwalk___build_toolchain_android_arm__rule
  command = python ../../build/symlink.py -f clang_x64/dump_syms microdump_stackwalk

It is not clear to me from the gn rules why microdump_stackwalk ends up being symlinked to dump_syms.
