relocatable-prog-wrapper: Fix compilation error on NetBSD 7

[Bruno Haible]

When building GNU libiconv with option --enable-relocatable, without
compiler optimizations (e.g. with CFLAGS=-g), on a platform that is
old or fringe (such as NetBSD 7), a compilation error occurs during
the 'make install' step, while linking the reloc-wrapper:

gcc -std=gnu11 -g -I../srclib -I../srclib -I.. -DHAVE_CONFIG_H 
-DIN_RELOCWRAPPER -DNO_XMALLOC -DINSTALLPREFIX=\"/home/bruno/inst\" 
-DINSTALLDIR=\"/home/bruno/inst/bin\" -DLIBPATHVAR=\"LD_LIBRARY_PATH\" 
-DLIBDIRS=\"/home/bruno/inst/lib\", -DEXEEXT=\"\" ../srclib/relocwrapper.c

`stat_time_normalize'
Makefile:113: recipe for target 'install' failed
gmake[1]: *** [install] Error 1

The cause is that the file srclib/stat-time.o, which defines the symbol
'stat_time_normalize' when not optimizing, is not part of the link.
This patch fixes it.
