shell: dash - large file support

[Aleksandar Ristovski <aleksandar.ristovski@xxxxxxxxx>]

Hello,

For builds that build 32-bit dash, configure misses to setup large
file support resulting in issues with large files.

For example:
...dp/dash-0.5.8/build$ ls -l /tmp/largefile.sh
-rw-rw-r-- 1 aristovski aristovski 3794653588 Jul 24 14:12 /tmp/largefile.sh
...dp/dash-0.5.8/build$ ./src/dash /tmp/largefile.sh
./src/dash: 0: Can't open /tmp/largefile.sh


Where dash was configured (on a 64-bit platform) like so:

...dp/dash-0.5.8/build$ CFLAGS=-m32 ../configure && make -j8


Now, if I make the change in configure.ac and reconfigure the project,
I get proper operation:

...0.5.8.patched/build$ ./src/dash /tmp/largefile.sh
Running...
...


(the actual working of the 'largefile.sh' is removed for brevity)


Thank you,

Aleksandar Ristovski
