The gcc directions for building gmp and friends should say that they must be configured and built with --disable-shared --enable-static if the user doesn't have the installed lib directory in their environment.

It's not confusing, it's right. gcc is not able to compile indeed.

I think it is user error. If your libraries are not in the right place,
either you rely on .la files and force everyone to use libtool (not a
good idea), or you put the paths in LD_LIBRARY_PATH/LD_RUN_PATH, or you
add flags manually to the configure line.
