There were two issues: the linux->darwin cross compiler is more stringent
about unused variables, and the makefile specified flags for building ON
darwin that were actually applicable whenever we are building FOR darwin.
Timezone code was broken in the Android class library bootimage build
because the code we use to intercept loading the tzdata file wasn't
working. The reason is have no way of intercepting static methods at
runtime in the bootimage build without telling the bootimage-generator
we're going to do it ahead of time. So now we do tell it so.
This commit also removes the need to intercept Thread methods since we
can update Thread.vmThread in VMThread.create instead.
This is necessary to avoid name conflicts on various platforms. For
example, iOS has its own util.h, and Windows has a process.h. By
including our version as e.g. "avian/util.h", we avoid confusion with
the system version.
