My mean is that rabuild the package and use the gcc CFLAGS="-march=armv6j -mfpu=vfp -mfloat-abi=hard" ,but the Raspberry pi so solwly. So I want to use two board Raspberry pi and run the MPI ,　so we can build and optimalize the packages.

so you are asking for parallel build, not cross compile, though both can speed up your build.

Please search the Internet for distcc.

you can also have a shot at x-build

# The purpose of this is to build enough of a toolchain that I can use
# distcc to a fast x86 host from my native ARM build hosts.
# This script does not build an entire cross toolchain and the result
# in /opt/arm is pretty messy (although could easily be tidied).
# 
# Additional scripts included:
#
# rc.local-addition: a method of starting distccd on the x86 host machines.
# dbuild: used on the ARM hosts as a wrapper for calling the Slackware ARM
# build scripts via distcc.  Instructions for usage are contained within the script.
