@Update to 0.6.0.1

Changelog:
[20140817]  Release 0.6.0.1. It has been a while since the last
release, and the SVN repository mirror at Sourceforge seems to be
broken, so it felt reasonable to package the current code into a
patch release. Not much has happened feature-wise since 0.6.0.

[20140816]  On FreeBSD/amd64 with GCC 4.2.1 as the default compiler,
you may need to install GCC 4.8.4 and run the configure script like
this to avoid triggering a bug in the default compiler:

CXX=c++48 CXXFLAGS=-Wl,-rpath,/usr/local/lib/gcc48 ./configure

[20110820]  Not much coding lately. The only thing worth mentioning
is that the Dreamcast emulation mode now gets further when running
Marcus Comstedt's test programs, and also shows "something" when
booting the PROM from my real Dreamcast. (This was in the legacy
Dreamcast mode, for fun. I haven't had time to work on the new
framework at all.)

[20100729]  Uploaded a clip to YouTube, showing the NetBSD/pmax
install procedure in GXemul.

@- try to enable big-endian mips support (from matt@@)
- add sh kernel-address-in-user-mode exception support (seems to work
  for me, but XXX: some sh person should really look at this.)
