I tried to find out what is causing this 'inconsistency'. (Please keep
in mind that I don't fully understand what I'm doing.) To me it looks
like the configure script tests if its executing shell is 'compatible
enough'. If this is not the case it looks for a better shell and
records its name in CONFIG_SHELL. If the script is happy with the
executing shell it doesn't touch the variable CONFIG_SHELL. It then
assigns the variable SHELL the value of CONFIG_SHELL with /bin/sh as
default.

So, if the shell that executes the configure script is bash the
varible SHELL will be set to /bin/sh.

It tried the following patch.

This helped in my case. So you think it might be useful in general?
