Just to wind this thread up, here's the status of RTEMS-4.10 toolchain on OS X.
The source files from http://www.rtems.com/ftp/pub/rtems/SOURCES/4.10/

1 -- OS X 10.6.8 (Snow Leopard) Host compiler -- i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5666) (dot 3)
	* Toolchains for m68k, i386, powerpc all build fine

2 -- OS X 10.7.1 (Lion) Host compiler i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)
	* The GMP and MPFR library tests lock up or seg-fault in various spots so I tried to continue by installing without running the tests.
	* Cross-compiler hits an abort().  Here's the salient output from m68k-rtems4.10/libgcc/config.log

	* This time the GMP and MPFR libraries build and test fine.
	* But the compile  fails:
../../gcc-4.4.6/gcc/toplev.c:536:1: error: redefinition of a 'extern inline' function 'floor_log2' is not supported in C99 mode

	* Try commenting out the inline function source in gcc-4.4.6/gcc/toplev.h -- but things still won't build.  This time the problem is an undefined symbol:

clang: error: linker command failed with exit code 1 (use -v to see invocation)

So the takeaway message is, "Don't use this version of OS X Lion if you want to use RTEMS-4.10".
