-Upgrading autoconf
-===============================================================================
-
-If you are in the mood to upgrade autoconf, you should:
-
- 1. Consider not upgrading.
- 2. No really, this is a hassle, you don't want to do it.
- 3. Get the new version of autoconf and put it in <SRC>
- 4. configure/build/install autoconf with --prefix=<PFX>
- 5. Run autoupdate on all the m4 macros in llvm/autoconf/m4
- 6. Run autoupdate on llvm/autoconf/configure.ac
- 7. Regenerate configure script with AutoRegen.sh
- 8. If there are any warnings from AutoRegen.sh, fix them and go to step 7.
- 9. Test, test, test.

-# Configuration subroutine to validate and canonicalize a configuration type.

-# If it is invalid, we print an error message on stderr and exit with code 1.
-# Otherwise, we print the canonical config type on stdout and succeed.

-#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
-# or in some cases, the newer four-part form:
-#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
