thanks for reproducer!
This _really_ looks like issue mentioned [1], though the thread is
believed to be resolved (with existing small slowdown between
libtool-2.4.5 and 2.4.2). Let me CC Robert whether this patch does not
actually fix the "1 sec" slowdown of libtoolize.

You can workaround/fix this by:
-m4_define([nginx_version], m4_include(nginx_version))
-NGINX_VERSION=nginx_version
+NGINX_VERSION=m4_include([nginx_version])
See the "recursion" in 'nginx_version' definition. Its not recursion
usually (because nginx_version is not defined in the time of m4_define)
-- but libtoolize script does 'm4_undefine(m4_include)' before
evaluating configure.ac.

I would say so, see the attached patch I'll push very soon (if there are
no objections).

Should be IMO reproducible everywhere.
