[ob] Allow ./configure for testsuite

[Daniel Jacobowitz <drow at false dot org>]

I accidentally committed this earlier in the week.  That's what I get for
leaving it in my working directory... however, I meant to do it eventually,
so I added a changelog entry and left the patch in (except for one temporary
comment which I reverted).

This patch fixes a bug where running "./configure" in the testsuite
directory would fail (or rather, make check would, afterwards).  It only
works if --host and --target are explicitly specified.  GCC has some handy
macros which give you the requested host if one was requested, and the
canonical one otherwise; that's exactly what we need here.

All the rest of aclocal.m4 was obsolete.
