Running '/lib/libc.so.6' on it should tell if there are any shared libs
and if, how the main one was produced...

Copying the complete glibc set onto the "cross" development host...

With a self-made cross GCC or with the native GCC from that 'old linux
desktop', my guess would be Red Hat 6.2 by your earlier message... The
GCC (egcs-1.1.2) binaries from RHL6.2 should work still on the uptodate 
Linuces...

But you had better to reveal more details, CPU arch etc., the Linux/x86
was mu guess...
