Fix to reduce the additional static testsuite failures with older glibc

[Alfred Minarik <alfred dot minarik at lion dot cc>]

As reported by others there are additional static testcase
failures with older glibc not compiled with current gcc.

And it is quite simple
we only have to use the correct order of libraries.

-----------------

This only leaves 
  27_io/ios_base_callbacks.cc
  27_io/ios_members.cc

I would like to add the observation, that doing a 
  make check-install
makes the last additional fails go away.
(This has improved in the last days, before with check-install 
I obseved no more fails in 21_string but new ones in 27_io) 

But this is erroneous:
After removing the dynamic libraries from the install directory it fails again:

Reason is an additional ld argument of -lstdc++ (probably) generated by g++
as we correctly do not use -nodefaultlibs in the check-install case.
So we seem to get some right bits from libstdc++.so in this case, even 
it is searched only after libstdc++.a .
See yourself:

-make check-install:

/usr/local/binutils/bin/ld -m elf_i386 -dynamic-linker /lib/ld-linux.so.2 
-o ./inserters_extractors.st-exe /usr/lib/crt1.o /usr/lib/crti.o
