[tex-live] byte-endian issue resolution fixes problem with common .fmt files

[Nelson H. F. Beebe]

Thanks to list members who worked hard on resolving the byte-endian
issue in loading common .fmt files into TeXware on multiple platforms.
Supplying the missing AC_C_BIGENDIAN in web2c/configure.ac and
rebuilding some of the binaries seems to have resolved the problem.

This morning, after updating our TeX Live 2009 tree from the master
copies, I regenerated all of the .fmt files on Solaris 10 SPARC, and
then ran TeX successfully on these platforms with identical .fmt
files:

	Sun Solaris 7 and 10 SPARC
	Sun Solaris 10 AMD64 and IA-32
	GNU/Linux AMD64/EM64T, IA-32, IA-64, SPARC
	Mac OS X PowerPC and AMD64/EM64T

The binaries for SGI IRIX MIPS have not been updated yet, so TeX does
not run on that platform with the newly-generated .fmt files.

We have one old system running GNU/Linux on Alpha (Gentoo Base System
version 1.4.16).  It is a rather old, but stable, O/S release, and we
plan to upgrade it later this fall.  TeX from TeX Live 2003, 2004,
2005, and 2007 run fine on it, but the TeX binaries from 2008 and 2009
produce this behavior (notice the lstat failure in the second and
later lines):

	lstat(.) failed ...

Does anyone else have a similar system that could be tested with the
2009 binaries?
