This is breaking all builds since ~9 PM last night.

Last good x86 build:
https://build.chromium.org/p/chromiumos.chromium/builders/x86-generic-tot-asan-informational/builds/11699

First bad x86 build:
https://build.chromium.org/p/chromiumos.chromium/builders/x86-generic-tot-asan-informational/builds/11700

Example bad amd64 build (has better logs, there were other infra issues that mean I can't tell the first bad build here):
https://build.chromium.org/p/chromiumos.chromium/builders/amd64-generic-tot-asan-informational/builds/10274

Strangely, the code lives in src/aosp/system/tpm and that repo hasn't changed since August 9.
