Tracing this a bit, I see the LINENO support introduced in dash 0.5.5.1-4
for #540685 makes configure think it's already running on a good enough
shell. On 0.5.5.1-3 it just does an 'exec bash ./configure'.

The above non-portable part comes from configure.in, so this is really
a bug in mapserver for using bashisms.

One workaround is to explicitly call 'bash ./configure' from debian/rules.
