Did you build toolchain and glibc yourself?
If yes, can you provide complete configure/ame/make install switches and
variable settings? (I'm interested in setting up cross compiler too,
bug hunting is a good opportunity).

Apparently your gcc doesn't allow calling one-argument macros with empty arguments.
Maybe try newer gcc? 2.xx.x is two major versions old...
