script was defaulting the LLVMGCC variable to "llvm-gcc" if it couldn't
find llvm-gcc and --with-llvmgccdir was not specified. In this case, there
is no llvm-gcc available on the system so we shouldn't assume that the
user's path will find it any better than configure could. The fix is to
default it to an empty string. If LLVMGCC is empty, the makefiles will
avoid building things that depend on llvm-gcc and give a nice warning
message to that effect.

--enable-target which can take values "all", "host-only" or a comma
separated list of target names (alpha,ia64,powerpc,skeleton,sparc,x86)

options have been added to the configure script that control which targets
will be used. The options are:

--enable-target-this (default=disabled)
  This will specify that the target corresponding to the build host is
  the target that will be compiled/used. You can't use this with any of
  the other options (they'll be ignored). This is what most people want.

--disable-target-x86 (default=enabled)
  This will prevent the X86 target(s) from being compiled/used.

--disable-target-sparc (default=enabled)
  This will prevent both SparcV8 and SparcV9 from being compiled/used.

--disable-target-powerpc (default=enabled)
  This will prevent the PowerPC target from being compiled/used.

--disable-target-alpha (default=enabled)
  This will prevent the Alpha target from being compiled/used.

--disable-target-ia64 (default=enabled)
  This will prevent the IA64 target from being compiled/used.

Note that without any of these options, the default behavior is to build
all targets, as is the current practice.

All these options do is set up the substititution variable TARGETS_TO_BUILD
which contains the targets that should be compiled/used. The variable is
intended to be used in the makefiles. Those changes will come later.
