Between 20050505 and 20050510, the ppc-eabisim configuration was broken. I'm seeing this error:

Some experimentation shows that the assembler from the two dates behaves the same,
and eabi.S is identical, but the preprocessed source files differ. cc1 used to define
_RELOCATABLE, but it does not any more.
The definition used to be:
# 0 "<built-in>" #define _RELOCATABLE 1
