$ sparc-elf-ld -V
GNU ld (GNU Binutils) 2.18
$ sparc-elf-gcc -v
Using built-in specs.
Configured with: ../configure --enable-targets=sparc-elf,sparc64-elf
--disable-nls --disable-threads --enable-multilib --enable-languages=c
--with-gnu-ld --with-gnu-as --disable-libssp --target=sparc-elf
Thread model: single
gcc version 4.2.4
IIRC GCC configure line was almost identical to binutils line.
$ sparc-elf-gdb -v
GNU gdb 6.8

This GDB was configured as "--host=x86_64-unknown-linux-gnu --target=sparc-elf".
There's no need for glibc, OpenBIOS is a fully freestanding target.
I'd also recommend using QEMU from git HEAD.
