The build system now allows incremental gem5 builds. Unfortunately,
the current solution always requires re-linking the executable.
Without the enforcement of re-linking, the fail code will be rebuilt
but not linked into gem5.

The number of cores for building gem5 is derived from /proc/cpuinfo.
As before, only the gem5.debug configuration is supported.

The recent information in how-to-use.txt and how-to-build.txt were
outdated.

Without --with-all-libs (as documented in doc/how-to-build.txt), at least
the "nogui" GUI does not work anymore -- the default for headless
experiments.

(Note the UNDEFINED->UNDEF enum rename; this was necessary due to a vga.h
include side-effect in bochs/gui/svga.cc.)

Bochs' configure options can now be set via ccmake.
