The lcms header files have some educated guesses for the current platform
big/little endianness, but they are not comprehensive (for example, PA-RISC
HP UX defeats it).
So, add a test to our configure scripts, and pass the setting as required as a
compiler option for lcms. NOTE: I added an explicit test for endianness because
the autoconf built-in test has problems in recent releases.
Also, noticed in passing: revise the other explicit compile/link tests to use
the AC_LANG_PROGRAM() macro - currently not doing so produces a warning, but
the implication is future versions will throw an error.
No cluster differences.

Recent Linux distributions defeat the check in unix-aux.mak for sys/time.h
with the hard coded path. So have configure check for it, and its
setting take precedence over the unix-aux.mak.
No cluster differences.

This revision disables checking for a system hypot() function and is
a followup to 7dcc68ce753175a9c686021d53a061253e2787c3 which modified
math_.h to always use our internal hypot() function.
No expected cluster differences.

As per bug 692211, add some autoconf magic to detect the presence of
__builtin_bswap32 and/or byteswap.h.

makefile. For some reason, as yet unexplored, the 64 bit I/O routine
configuration definitions break the build on some systems.

switch build. It is a bit unconventional - autoconf generates
config.mak (not Makefile) which is then included by pcl6_gcc.mak.
Only a few configuration options have been moved to autoconf so far,
we'll do this incrementally. The generated file config.mak is
included in this commit for backward compatibility with using only
make without configuration tools.
