Cleanup on AC_MSG_ERROR

[Pavel Roskin]

Hello!

AC_MSG_ERROR is almost always called "unexpectedly", i.e. inside tests, so it's
a good idea to clean temporary files before exiting.

This patch is needed to make my next patch to the testsuite work on systems e.g.
without Fortran 77 compiler.

Temporary files shouldn't be used for debugging. Either config.log should be
used, or (in very hard cases) configure should be edited to copy temporary files
at a known point. So please don't worry about too many rm's - they will never
have to be conditional.

Regards,
Pavel Roskin
