You don't need to alter the AC_TRY_RUN. AC_TRY_RUN are just the  
configure tests that won't get a correct result when the build arch  
is not the same as the target arch. Take a look at configure.in and  
search out the AC_TRY_RUN checks. These will all be wrapped in an an  
AC_CACHE_CHECK. The second argument to the AC_CACHE_CHECK macro is  
the name of the variable whose value you need to preload.

Here is the first few line from the config.site that I use:

samba_cv_HAVE_Wdeclaration_after_statement=yes
samba_cv_HAVE_Werror=yes
samba_cv_HAVE_w2=yes

You would then run configure like this:

	CONFIG_SITE=config.site ./configure ---blab --blah

Set samba_cv_HAVE_KERNEL_OPLOCKS_LINUX=no in your config.site. If  
this doesn't let you build, then it's a bug.
