By definition, prebuilt packages are compiled binaries (if there ever were a redundant phrase...). Compiled programs use the CHOST they're compiled with. If it's a generic one that your system supports, then it'll work on your system. Constrastingly (is that a word?), if you compile, say a program with sse2 optimizations and said program requires it, and you use it on a a system that doesn't have sse2 (like an AMD K6-2), it won't work. At least, this is my understanding from RTFL I gave you.
