Ah....
Building with "make  ARCH=3Dparisc  CROSS_COMPILE=3D/some/path/nolibc/hppa=
-linux/bin/hppa-linux-"
uses this CROSS_COMPILE prefix for compiling the .c files, but not for the=
 .S files.
So, you will end up with the default hppa-linux-gcc installed on the syste=
m, not the one provided
by CROSS_COMPILE.
