Summary:
Longstanding issues in the Android test runner means that compiler-rt unit
tests don't work on Android due to libc++ link-time issues. Looks like the
exported libc++ from the Android NDK is x86-64, even though it's part of the
ARM[64] toolchain... See similar measures for ASan and sanitizer-common that
disable unit tests for Android.
Should fully fix the Android bots (@vlad.tsyrklevich).

to try and fix android buildbot. Also make sure that the empty dummy
test contains an output file name so the android_build.py wrapper script
doesn't check fail.

Summary:
See D60593 for further information.
This patch pulls out the mutex implementation and the required definitions file.
We implement our own mutex for GWP-ASan currently, because:
1. We must be compatible with the sum of the most restrictive elements of the supporting allocator's build system. Current targets for GWP-ASan include Scudo (on Linux and Fuchsia), and bionic (on Android).
2. Scudo specifies `-nostdlib++ -nonodefaultlibs`, meaning we can't use `std::mutex` or `mtx_t`.
3. We can't use `sanitizer_common`'s mutex, as the supporting allocators cannot afford the extra maintenance (Android, Fuchsia) and code size (Fuchsia) overheads that this would incur.
In future, we would like to implement a shared base mutex for GWP-ASan, Scudo and sanitizer_common. This will likely happen when both GWP-ASan and Scudo standalone are not in the development phase, at which point they will have stable requirements.
