we also provide -mno-ieee.

Index: 42_all_superh_default-multilib.patch
===================================================================
The gcc-3.x toolchains would contain all the targets by default.  With gcc-4,
you have to actually list out the multilibs you want or you will end up with
just one when using targets like 'sh4-linux-gnu'.

The resulting toolchain can't even build a kernel as the kernel needs to build
with the nofpu flag to be sure that no fpu ops are generated.

Here we restore the gcc-3.x behavior; the additional overhead of building all
of these multilibs by default is negligible.

Index: 74_all_gcc49_cloog-dl.patch
===================================================================
dlopen cloog-isl library rather than link to it directly.  This prevents
cloog upgrades that change the soname from breaking the compiler.

http://pkgs.fedoraproject.org/cgit/gcc.git/tree/gcc49-cloog-dl.patch


In FreeBSD dlopen is part of libc so we can't just hardcode -ldl.

2014-04-30  Ryan Hill  <rhill@g.o>

    * configure.ac (DL_LIB): Set to ac_cv_search_dlopen.
    * configure: Regenerate.
    * Makefile.in (BACKENDLIBS): Use DL_LIB.
