Hongxu Jia - July 9, 2013, 12:30 p.m.
Add checksum files required for the NSS softoken to operate in FIPS 140 mode.
The shlibsign is invoked to sign the libraries, and it is built for the target
architecture and doesn't support cross-compiling so far.

Invoke shlibsign at target's boot time to generate checksum files.
