-configure.ac: fixup LFS check for autoconf-2.72
-
-For the 'other' case, we were using the value of ac_cv_sys_file_offset_bits for
--D_FILE_OFFSET_BITS to pass down into the Perl module build, but autoconf-2.72
-drops the use of ac_cv_sys_file_offset_bits in cf09f48841b66fe76f606dd6018bb3a93242a7c9,
-so this ends up defining '-D_FILE_OFFSET_BITS=' which then breaks the build.
-
-I've just added a hack to preserve the old behaviour to avoid passing a blank
-value.
