I cross-compiled an arm kernel from linux-source-2.6.21 using make-kpkg. After installing it on my Linksys NSLU2, the system became unbootable. Here is the console output:

libgcc_s.so.1 must be installed for pthread_cancel to workKernel panic - not
syncing: Attempted to kill init!
Adding libgcc_s.so.1 to the initramfs and reflashing it solved the problem.
