I want my testsuite to be relocatable too.  But if I generate hardcoded 
`AC_CONFIG_AUX_DIR([../../config])', I need to remember to edit that line (in 
every test!) if I move the tests.  Alternatively I could have a different 
AUX_DIR (and MACRO_DIR, and maybe others) for each test group... but that 
seems like a lot of duplicated files.

Why is it bad to want to do it this way?

I'm not sure I follow.  In libtool, there is already $top_srcdir/config, and 
$top_srcdir/m4 (which contains the shipped libtool.m4), I've managed to 
eliminate the 14 copies of libtool.m4 we used to ship thanks to m4_include in 
the latest Automake.  Can my store be $top_srcdir/m4? ;-)

Cheers,
        Gary.
