gcc 4.2.1 for arm & mips?

Hi. Specifically, I'm attempting:
gcc-4.2.1 (have been using 3.4.6 with all the other bits below the same)
crosstool-0.43
binutils-2.17
glibc-2.3.6 (using linuxthreads)
for mips:
* gcc configured with --with-float=soft --with-arch=mips32
--with-tune=mips32 --with-endian=little and a bunch of other stuff (see
below)
* glibc configured with --without-fp and other stuff
for arm:
* gcc configured with --with-float=soft --with-cpu=xscale
--with-endian=little
* glibc configured with --without-fp and other stuff
On mips, the glibc stage of the build fails with:
In file included from
../linuxthreads/sysdeps/unix/sysv/linux/mips/sysdep-cancel.h:22,
from ../sysdeps/unix/sysv/linux/mips/pread.c:29:

Error 1
The source line in question is:
result = INLINE_SYSCALL (pread, 6, fd, CHECK_N (buf, count), count, 0,
__LONG_LONG_PAIR (offset >> 31, offset));
(I haven't dug into the macros yet, but I'm sure it's inline asm.)
On arm, after applying a patch for raise in linuxthreads and a patch for
floating point, I get complaints about multiple defs of __floatundisf,
__floatdidf, etc. I'll dig into that next.
I just wanted to see if anyone else had already come up with patches for
this stuff before I go spend a bunch of time on it - this task is
tangential to what my job is supposed to be. Anyone? Any pointers
would be appreciated. (Snide remarks to /dev/null, please - you know
who you are. My understanding is that this list is for folks to HELP
each other, and post patches and the like.) I've googled but not found
much that helped.
On that topic, it would be very nice if we could somehow arrange for
patches that are submitted (e.g., for newer versions of gcc, glibc,
etc.) to appear in crosstool (at least in svn) a bit more promptly.
Perhaps Dan could delegate if he's too busy??
