 Version: tor-browser-linux32-3.0-alpha-3_en-US

 When start-tor-browser is run from a location other than within its
 directory (eg, it is not invoked as ./start-tor-browser), the architecture
 check introduced for #3841 looks for tor at the wrong path and fails with
 a message like this:
 {{{
 ./Downloads/tor-browser_en-US/start-tor-browser: 123: [: -ne: argument
 expected
 }}}

 The check fails open, though, so after that error is printed everything
 still works (assuming the architecture is correct).

 Replacing this:
 {{{
 TORARCHITECTURE=$(expr "$(file App/tor)" : '.*ELF \([[:digit:]]*\)')
 }}}
 With this:
 {{{
 TORARCHITECTURE=$(expr "$(file $(dirname $0)/App/tor)" : '.*ELF
 \([[:digit:]]*\)')
 }}}
 should fix the problem.
