This should work on all GNU variants, so you should be testing whether
$(uname -o) contains “GNU”.

Example:

--8<---------------cut here---------------start------------->8---
ludo at goober:~$ uname -a
GNU goober 0.3 GNU-Mach 1.3.99/Hurd-0.3 i386-AT386 GNU
ludo at goober:~$ uname -o
GNU
ludo at goober:~$ uname 
GNU
ludo at goober:~$ ls -l /lib/ld-2.9.so 
-rwxr-xr-x 1 root root 138156 Oct  1 06:41 /lib/ld-2.9.so
ludo at goober:~$ /lib/ld.so /bin/bash --version
