[Bug-pyconfigure] [PATCH] m4: fix broken redirection to AS_MESSAGE_LOG_FD

[Duncan Burke]

There were were three separate problems with the usage of AS_MESSAGE_LOG_FD:

* ./configure was erroneously producing files named with the fd number
  due to the missing ampersand.

* /bin/sh does not accept whitespace between redirection terms.

* It is invalid to append to an fd in this manner. A straight redirection
  gives the desired result.
