Permission denied on a.out in ./configure

[Clayton Daley]

I totally understand and don't expect you to move mountains for an edge
case, but I don't mind reporting "maybe you care" issues either.

Incidentally, a fix at my end was to replace "./a.out" with "sh ./a.out" in
configure.  The rest of the process ran fine (except, the final make
install since I don't have permission).  The "better" approach -- of course
-- would have been to extend the lines that check "./a.out" with additional
"or"s for the same files using "sh" (but I didn't need to preserve the
original checks).

Up to you whether this kind of edge case is worth gumming up the configure
file.
