put -lpthread into LIBS instead of CONFIG_LDFLAGS.

Browse Source 
The problem showed up on AIX when we switched from the system linker
to GNU ld. What happens is that configure is adding -lpthdebug to
CONFIG_LDFLAGS when AIX thread debugging support is detected.  But
this causes the "-lpthread" switch to be placed at the _before_
GDB's .o files (see Makefile.in):

    INTERNAL_LDFLAGS = [...] $(CONFIG_LDFLAGS)
    [...]
    gdb$(EXEEXT): gdb.o $(LIBGDB_OBS) $(ADD_DEPS) $(CDEPS) $(TDEPLIBS)
            rm -f gdb$(EXEEXT)
            $(CC_LD) $(INTERNAL_LDFLAGS) $(WIN32LDAPP) \
                    -o gdb$(EXEEXT) gdb.o $(LIBGDB_OBS) \
                    $(TDEPLIBS) $(TUI_LIBRARY) $(CLIBS) $(LOADLIBES)

And as a result of this, the linker reports an error due to some
symbols in aix-thread.o not being satisfied.

This patch adds the "-lpthread" switch to LIBS instead, which should
be the right place to add it.
