[gentoo-user] Compile program with older libraries

Hi!

I have some program which I am using in a thin client  which has Gentoo
stage 3 root fs (kernel 2.6.39.4),
lets call it system A.
I've also compiled that program chroot-ed in this stage 3 fs from my
personal computer.

I have an other thin clients which have older system (B) on it which is
older linux kernel 2.6.16.27.
Library version which are needed are of course different and for that
reason my program
can not be run in this sistem.

System A:
Linux redondo 2.6.39.4 #18 Mon Mar 19 13:14:32 CET 2012 i586 i586 i386
GNU/Linux
/lib/libc-2.12.2.so
gcc version 4.0.3

System B:
Linux carlos  2.6.16.27 #1 Sun Mar 25 11:09:40 CEST 2007 i586 i586 i386
GNU/Linux
/lib/libc-2.3.6.so
gcc version 4.0.3

Shared libraries that my binary uses are (in system A):
linux-gate.so.1 =>  (0xffffe000)
libpthread.so.0 => /lib/libpthread.so.0 (0xf76d6000)
libuuid.so.1 => /lib/libuuid.so.1 (0xf76d1000)
libstdc++.so.6 => /usr/lib/gcc/i486-pc-linux-gnu/4.4.5/libstdc++.so.6
(0xf75da000)
libm.so.6 => /lib/libm.so.6 (0xf75b2000)
libc.so.6 => /lib/libc.so.6 (0xf7468000)
/lib/ld-linux.so.2 (0xf76f3000)
libgcc_s.so.1 => /usr/lib/gcc/i486-pc-linux-gnu/4.4.5/libgcc_s.so.1
(0xf7449000)

If i try to compile my program using '-static' directive, I still have a
problem with 4 functions:
-initgroups,
-getpwnam,
-getaddrinfo,
-gethostbyname.

If I got that right, they use functions which are located in NSS shared
libraries.

I am looking for a way of compiling my program so that I can run it in
system B.
I have libraries available from system B and that is all that I have.

I need help on getting this done.
I guess gcc versions are the same and as well libgcc_s.so.1 shared library.

My questions are:
Can I pull those libraries from system B and use it in compilatin process?
Would that work?
I would still need to get include source files of that version, right?
Is there some archive site where I can find so old version of linux kernel
source?
One thing that pops in to my mind is also trying to find gentoo stage 3
tarball of the kernel version 2.6.16.27
and compile the program there...I tried to search that but no luck in
that...

Any help would be welcomed!
