With both 4.6.3 and trunk, I'm seeing problems with libquad, which is
completely baffling me.  The 'gmake bootstrap' completes as expected,
but 'gmake install' dies with 

gfortran.so.3.0 -o .libs/libgfortran.so.3.0
/usr/bin/ld: /home/sgk/work/46/lib/libquadmath.a(fmodq.o): relocation
R_X86_64_32S against `a local symbol' can not be used when making a shared
object; recompile with -fPIC
/home/sgk/work/46/lib/libquadmath.a: could not read symbols: Bad value

libtool: install: error: relink `libgfortran.la' with the above command before

I've redirected the the output to files and the -fPIC is already on
the command line.  What seems odd to me is that the 'gmake install'
is relinking the libquadmath.so shared library.  I've attached
'gmake |& build.log' and 'gmake install |& install.log'
