Hi folks,

Previous GCC library paths are baked into libtool!

Belated rediscovery of a previously used "feature".

As ncurses is baked with a specific autoconf version 2.52, it can not be 
autoreconf-ed, but includes a fixup script to hack /usr/bin/libtool to update 
library paths to the latest GCC major version!

Enabled execution of fixup script hack against libtool during each run to avoid 
any future issues!

Not sure why libtool could not be written to use `gcc -dumpversion`, the path 
search expression in the fixup script, or the autotools/gnulib 
LT_INIT/AC_PROG_LIBTOOL/AM_PROG_LIBTOOL machinery to set the appropriate path?

Sheesh! Sorry for the noise!
