This avoids link errors of some tests in gnulib-tests on Cygwin and mingw

both with gcc and cc) in 32-bit mode.

Reported by Kiyoshi KANAZAWA <yoi_no_myoujou@yahoo.co.jp> in
<https://lists.gnu.org/archive/html/bug-gettext/2020-07/msg00034.html>.

configure.ac interfered with each other (through the GNULIB_* indicator macros,
used in the generated .h files), and libgrep relied on it. Now, each gnulib-tool
invocation needs its own copy of the generated .h files, in particular locale.h.
Needed for the localeconv() override on native Windows.

the other header file modules.
