LD_LIBRARY_PATH=/mydir/gmp/lib:/mydir/mpc/lib:/mydir/mpfr/lib

LD_LIBRARY_PATH is bad (*). If you use it for anything else but patching libraries into a system for test / workaround purposes, chances are you are mis-using it.

Either

• using the host system's GMP and MPFR, or
• building GMP and MPFR in default directories (/usr/... or /opt/...), or
• putting their sources into the GCC source tree and build them alongside everything else

works (unless you're playing dork like I did). Each option is preferrable to setting LD_LIBRARY_PATH.
