m4: Utilize AS_VAR_APPEND
* m4/libtool.m4: Instead of a conditional for using -no_fixup_chains,
AC_VAR_APPEND will handle appending the option to the variable, which
allows the '+=' extension to be used by shells that provide this
capability for more efficient scaling. Also, bump minimum required
version of autoconf from 2.62 to 2.64.
