[PATCH] allow cross-compiling samba-2.2.7

[Dan Kegel]

I needed to cross-compile Samba for ppc linux from x86 linux.
Fortunately, samba-2.2.7 is very nearly cross-compile-friendly.
The main problem when cross-compiling autoconf'd projects is AC_TRY_RUN
in configure.in, which just doesn't work.  Sure enough, to get
Samba to build in a cross-compilation environment, all I had
to do was get rid of one use of AC_TRY_RUN in configure.in,
run autoconf2.50 (to generate a configure script that sets
SIZEOF_INT without using AC_TRY_RUN), and run configure like this:

CC=/opt/cegl-1.4/hardhat/devkit/ppc/405/bin/powerpc-linux-gcc CFLAGS="-mcpu=403" 
../samba-2.2.7/source/configure --build=pentium-unknown-linux --host=ppc-unknown-linux

Here's a patch that removes the one use of AC_TRY_RUN in configure.in
that was causing trouble.  (And oddly, this makes the definition of
HAVE_GETTIMEOFDAY_TZ better match how this macro is used in the sources,
I think.)  Please apply if you agree it's benign.  Thanks!
