We can fix this with a trick from hpa in the x86 code, we # statically check the type of x and set the type of __gu_val to either # unsigned long or unsigned long long. # # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/hppa-linux/bin/hppa-linux-gcc --version # < git log --format=%s --max-count=1 f7a6947cd49b7ff4e03f1b4f7e7b223003d752ca # < make -s -j 48 ARCH=parisc O=/kisskb/build/powerpc-next_parisc-defconfig_parisc CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/hppa-linux/bin/hppa-linux- defconfig # make -s -j 48 ARCH=parisc O=/kisskb/build/powerpc-next_parisc-defconfig_parisc CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/hppa-linux/bin/hppa-linux- /kisskb/src/net/Makefile:24: CC cannot link executables.
