If neither MAJOR_IN_MKDEV or MAJOR_IN_SYSMACROS is defined then provide
our own implementation of these macros locally. This complements the
change in commit cf5ad183 (Fix major() check for LSB 4.0, 2011-01-12).
This patch is based on upstream libarchive SVN commit 1553 (Shuffle the
major/minor/makedev support a bit; this should work on both Windows and
Haiku, 2009-10-31).
