Hi,
When building a libiconv snapshot with --enable-relocatable on Cygwin,
"make install" fails with
libtool: link: gcc -g -O2 iconv.o iconv.res -o .libs/iconv.exe

This is caused by the fix from
http://lists.gnu.org/archive/html/bug-gnulib/2014-08/msg00001.html
that was added on 2014-08-07. It contained several mistakes:
- Adding strerror-override.c to the compilation runs against the intent of
the change from 2011-05-21
relocatable-prog-wrapper: Assume strerror() exists.
- Some .o files were not removed.
- Source files were not listed in module description.
Additionally, my change from 2011-05-21 also had two mistakes:
- It should have done
#undef strerror
to avoid dragging in rpl_strerror.
- It should have removed the dependency to the 'intprops' module.
This fixes it.

relocatable-prog-wrapper: Fix breakage on Cygwin.
* modules/relocatable-prog-wrapper (Files): Add lib/stat.c, lib/lstat.c.
(Depends-on): Remove intprops.
* lib/relocwrapper.c: Update dependency tree.
(strerror): Undefine.
* build-aux/install-reloc (func_create_wrapper): Do not compile
strerror.c and strerror-override.c. Erase stat.o and lstat.o.
