[PATCH] build: fix race in parallel builds

[Hongxu Jia]

The automake-$(APIVERSION) is a hardlink of automake, if it is
created later than update_mans executing, there is a failure
[snip]
|: && mkdir -p doc && ./pre-inst-env /usr/bin/env perl
../automake-1.16.1/doc/help2man --output=doc/aclocal-1.16.1
aclocal-1.16
|help2man: can't get `--help' info from aclocal-1.16
|Try `--no-discard-stderr' if option outputs to stderr
Makefile:3693: recipe for target 'doc/aclocal-1.16.1' failed
[snip]

The automake_script is required by update_mans and update_mans
invokes automake-$(APIVERSION) rather than automake to generate
doc, so we should assign `automake-$(APIVERSION)' to automake_script.

The same reason to tweak aclocal_script.

* bin/local.mk: correct automake_script/aclocal_script
