autogen-native: fix POSIX_SHELL and perl

The shebang's length is usually 128 as defined in /usr/include/linux/binfmts.h:
  #define BINPRM_BUF_SIZE 128

So there would be errors when /path/to/hosttools/perl is longer than 128.

This patch fixes the problem when POSIX_SHELL and perl are used as the interpreters.

+Subject: [PATCH] autoopts/mk-tpl-config.sh: fix perl path
+
+Use "which perl" as shebang doesn't work when it is longer than
+BINPRM_BUF_SIZE which is 128 usually. So use "/usr/bin/env perl" to
+instead of.
