sorry if I don't understand correctly. 

what do you mean by "only for use with the compiler, not the target libraries."

download_prerequisite grab gmp and compile gcc suite using this one, so why
produced libraries are linked to external gmp ? 

IMHO produced gcc should linkk to "embeded" gmp downloaded by
contrib/download_prerequisites

this way one can compile on a build machine with a complete toolchain, tar the
installed tree and deploy it on an other machine (same arch and so on) that
does not have system gcc, gmp installed. 

currently this is not possible. 

please correct me if I am completely wrong
