Bash behaves differently when called as sh, to avoid just this sort of
problem. However, if the script calls /bin/sh while requiring bash
features it is clearly broken and a bug should be files.

Unfortunately, this type of breakage is all too common; I tried using
dash as /bin/sh for a short while and found all sorts of things falling
over. In this case, it can be easily fixed, by the ebuild altering the
shebang line of configure before running it.
