Yes. I see the same error under linux.
I have tried to fix this by revising the normal (not cross-compilation) definition
in configure.in from
CC_FOR_BUILD = "\$(CC)"
to
CC_FOR_BUILD = "{CC}"
That works for me here, but I am not confident that it is the correct fix.
This is beyond my depth of knowledge for autoconf/automake.
cc'ed to Robert Schwebel, author of the cross-compilation patch.
