Disable ParserSync test for now, it takes waaaaay too long.
...
Running this in x64.release mode on a powerful HP620 takes 4 seconds,
this is at least 2 orders of magnitude too slow and leads to tons of
false positives on our build bots due to timeouts. As it is, the
cost-benefit ratio is far too low.
The whole approach needs to be changed: Instead of trying to exhaust
some search space in unit tests, this should be turned into a fuzzing
test where only a small but random number of things are tested. The
exhaustive approach can be done separately, but definitely not in the
unit tests.

cctest/test-threads/ThreadJoinSelf is suppressed for Android, but the
test has since been moved to unittests/Thread.SelfJoin. Move the
suppression to unittests.status.
unittests/ThreadLocalStorageTest.DoTest fails on older Android devices
as it assumes the availability of more TLS slots than many devices
implement. Test a smaller number of slots (32) on Android. Remove old
suppression of test-platform-tls/FastTLS (which no longer exists).
cctest/test-mark-compact/RegressJoinThreadsOnIsolateDeinit can't deal
with shared mappings. Check for 's' instead of '-'.

The file snapshot_blob_host.bin was supposed to be generated when building the host toolset. However, the file snapshot_blob.bin was being generated instead, under every set of conditions.
...
Because of this, every time we build the host toolset, snapshot_blob_host.bin is not found. This causes the target (v8_external_snapshot) that generates such file to be run. This target generates snapshot_blob.bin instead of snapshot_blob_host.bin. This in turn causes all the targets that depend on snapshot_blob.bin to run again.
After this, we still don't have snapshot_blob_host.bin. So the next time we build, the whole process described above happens again.
