Subject: [PATCH] Define top_build_prefix fro use by LTDL

Linux LTDL v3-v7 macros assume the autoconf 2.62 variable top_build_prefix
is defined. But from autoconf 2.64 it's called ac_top_build_prefix and not
automatically added to the Makefile.

There seems to be no harm with sustituting it manually under autoconf 2.61 and 2.62
