* If compiling on X86 or Sparc, automagically enable the JIT for that arch
* Setting ENABLE_X86_JIT or ENABLE_SPARC_JIT on the `make' command-line will
force the inclusion of that JIT on a different architecture
* If neither JIT is enabled (e.g., compiling on a different architecture), the
-march option will not be available to LLI.
* As a side effect of the $ARCH variable, the Sparc LLI can now link just a bit
faster by not including the x86 library.
