[PATCH] for review - making use of {EXEEXT} more uniform in makefiles.

I humbly submit my first patch for feedback and consideration.  My
apologies in advance if I am not following the proper protocol for a
patch email, I'm new to this (I did look at several other [PATCH]
emails.)

Rationale: I'm porting Emacs to a new platform, and we need to have a
file extension on all
executables for this platform when we run the executables. In several
places in the makefile,
no extension is used.  This catches the places that I ran into, and
uses the {EXEEXT}
extension to make sure the proper file name extension is used to
launch programs by.

Motivating case:
I'm porting Emacs to the Chromebook using the NaCl API, and we need
for executables to have the .nexe extension.  Even when running Emacs
during the build process on the host Linux build machine  (for
instance to create leim-list.el or build documentation), we need the
proper extension so that the machine emulator is not confused.

I have tested this by building and running Emacs on Ubuntu 14 (only),
let me know if it is expected to test in more places.

All feedback and comments are welcome.

Subject: [PATCH] Use {EXEEXT} more uniformly in makefiles when running
 executables.

When porting Emacs to run on NaCl, we need to make sure that we always
call it with the proper extension (.nexe in this case) during the build,
when Emacs has to run to generate leim-list.el and documentation.
