--- Comment #230 from John Buddery <jvb at cyberscience dot com> --- The mpfr issue seems to be an issue with gcc 4.9.2 compiling later mpfr versions. It builds with 4.7.2, so as a workaround try building mpfr outside the gcc tree using 4.7.2. This may mean you need to build gmp and mpc outside the tree as well. I don't know about the ld crash - see if it occurs when building 11.1 after you get past the mpfr issue. If it does, that binutils patch will probably work with older binutils versions, so you might be able to find one compatible with your ld. I don't think it's the patch itself, as that only affects brl instructions which gcc won't be generating until the 11.1 patch.
