32 bits Vs 64 bits

[Tobias Speckbacher]

uname -a should reveal the architecture the kernel was built for.

another way to check would be getconf WORD_BIT which returns the size of
long (32 or 64).

On the app side, i am not sure how to check if you are dealing with a 32
or 64 bit app, of course the rpm itself should have a target
architecture referenced in its file name.
