This is a port of hourglass, a synthetic real-time application that
can be used to learn how CPU scheduling in a general-purpose operating
system works at microsecond and millisecond granularities.

- It creates very detailed map of when each Hourglass thread has
  access to the CPU

- It supports multiple thread execution models; e.g. periodic and
  CPU-bound

- It acts as an abstraction layer for threading, timing, and CPU
  scheduling functionality on Unix- and Win32-based systems

Update CONFIGURE_ARGS for how we pass CONFIGURE_TARGET to configure script.
Specifically, newer autoconf (> 2.13) has different semantic of the
configure target. In short, one should use --build=CONFIGURE_TARGET
instead of CONFIGURE_TARGET directly. Otherwise, you will get a warning
and the old semantic may be removed in later autoconf releases.

To workaround this issue, many ports hack the CONFIGURE_TARGET variable
so that it contains the ``--build='' prefix.

To solve this issue, under the fact that some ports still have
configure script generated by the old autoconf, we use runtime detection
in the do-configure target so that the proper argument can be used.

Changes to Mk/*:
 - Add runtime detection magic in bsd.port.mk

- Update maintainer address

Only compile on i386 and amd64, due to requirement for rdtsc() function.

- FreeBSD patches to include <machine/cpufunc.h> to get rdtsc() function,
  instead of using local one in hourglass.h.
- Other minor amd64 compilation fixes.

- respect PTHREAD_LIBS and PTHREAD_CFLAGS
- add WITH_LINUXTHREADS tunable to override PTHREAD_LIBS and PTHREAD_CFLAGS
  with linuxthreads port

At Kris's request, back out the MACHINE_ARCH spelling correction until
after 5.4-RELEASE.

Assist getting more ports working on AMD64 by obeying the
Ports Collection documentation and use 'ARCH' rather than 'MACHINE_ARCH'.

Add hourglass 1.0.0, a real-time application useful to learn how
CPU scheduling works.
