[Bug libfortran/18496] New: Build fails with "libgmp.so.6 not found" error

["jim at dishaw dot org" <gcc-bugzilla@gcc.gnu.org>]

I have libgmp and libmpfr installed with an atypical prefix (not /usr/local or
/usr) on the build machine because I do not have adminstrative rights.  I
invoked configure as

../gcc/configure --with-mpfr=/sys/sdf/sci --with-gmp=/sys/sdf/sci
--prefix=/sys/sdf/sci

The build progresses normally for a great while and then dies with the error

Examining the config.log in libgfortran, I found the following error
