ip2k-elf doesn't build. The build process fails while building gcc.
Specifically, __gcc_bcmp hits an ICE like so:
/home/kazu/gnu/gcc/gcc-develop/gcc/gcc/libgcc2.c: In function
$-1��__gcc_bcmp��:

Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
Here is a testcase, derived from a preprocessed source.
typedef unsigned int size_t;
int
__gcc_bcmp (const unsigned char *s1, const unsigned char *s2, size_t size)
{
while (size > 0)
{
const unsigned char c1 = *s1++, c2 = *s2++;
if (c1 != c2)
return c1 - c2;
size--;
}
return 0;
}
