simplechrome builders fail to find clock_gettime() (glibc version mismatch?) |

Issue descriptionThe chrome pfq is red for at least this reason.

Which builder exactly? (link?) On the pfq it started happening at refs/tags/52.0.2740.2. There were also a bunch of chromeos changes. I am attempting to reproduce locally now.

ihf@ marking this P0 and releaseblock-dev since this is blocking M52 branch.

I couldn't get this to fail locally, even using gyp. Since it is failing on a chromium builder also (https://uberchromegw.corp.google.com/i/chromeos/builders/x86-generic-chromium-pfq) I can try a bisect. Bisect builds are here (starting with 52.0.2740.2 which should fail and 52.0.2740.0 which should pass): https://uberchromegw.corp.google.com/i/chromiumos.tryserver/builders/chromium-pfq

I have no repro so far either.

I strongly suspect this CL as the root cause: https://chromium-review.googlesource.com/#/c/330900/ I see a bunch of compiler warnings that do not exist prior to that CL (not to mention the link failure).

Seems like this is resolved (e.g. PFQ did not fail with this error after fix landed) Anything else pending on this one?
