I could reproduce the error with lfs-7.5-rc1 as the host, by removing libgmp.la.
Actually, neither Debian nor Arch provide those .la files. I have not checked Fedora yet. I am not sure what should be done. If users accept to install libgmp-dev, libmpfr-dev, libmpc-dev on their host, the easiest would be to completely remove the build of those packages for gcc-pass1. I'll try that. This would imply that the host requirement be augmented with both libraries _and_ headers checks. Otherwise, maybe just a note telling to remove the .la files (completely removing them gives the cleanest build), at least for the course of the build?
