But, I think what threw me (and Hazel) off is why does the MPFR build process attempt to link against libquadmath in the first place? After all, as you said, libquadmath won't be available (in /usr/lib) until after gcc is (re)installed in step 6.20.1 So, MPFR's configure detects libquadmath (in /tools/lib) and then links its tests against libquadmath, but those tests later fail because the dynamic linker is set to link from what is in /usr/lib? In short, does the presence or absence of libquadmath affect the actual libmpfr.so or just its test executables - that without libquadmath the tests would not be linked against it and yet they still work fine? Does it affect, say, the number of tests that are done? Depending on the answer here, there may be a case for reinstalling MPFR again after gcc.
