For me, with your script, this fails with two errors:
gllib/Makefile.am:34: @LTALLOCA@ used but `LTALLOCA' is undefined
gllib/Makefile.am: object `pt_chown.$(OBJEXT)' created both with libtool and 

I'm applying these two fixes to gnulib-tool. With this, I think you should be 
to get a bit further, and remove this code from your script:

    for f in $(egrep '_PROGRAMS *=' ${TARNAME}/Makefile.am | sed 's/.*= *//')
        sedcmd=${sedcmd}$'\n'"/^EXTRA_${TARNAME}_la_SOURCES *+= *${f}\\.c/d"
    sed -i -e "${sedcmd}" ${TARNAME}/Makefile.am

This is just a warning that you can ignore.

Btw, in version.h the size of _libposix_git_version should not be exported
since it can change from one version to the next. So I would change
  extern char const _libposix_git_version[sizeof(_GIT_VERSION)];
  extern char const _libposix_git_version[];

        gnulib-tool: Fixes for --create-testdir with --libtool.
        * gnulib-tool (func_get_automake_snippet): Don't augment
        EXTRA_lib_SOURCES for the pt_chown module, since pt_chown.o goes into
        an executable.
        (func_create_testdir): Handle module 'alloca' like func_import.
        Reported by Bruce Korb <address@hidden>.
