can't compile this, I get the following error:

make CONFIG_OF_ALL_DTBS=y CONFIG_DTC=y HOSTCC=/home/fabio/0day/clang/bin/clang CC=/home/fabio/0day/clang/bin/clang LD=/home/fabio/0day/clang/bin/ld.lld HOSTLD=/home/fabio/0day/clang/bin/ld.lld AR=/home/fabio/0day/clang/bin/llvm-ar NM=/home/fabio/0day/clang/bin/llvm-nm STRIP=/home/fabio/0day/clang/bin/llvm-strip OBJDUMP=/home/fabio/0day/clang/bin/llvm-objdump OBJSIZE=/home/fabio/0day/clang/bin/llvm-size READELF=/home/fabio/0day/clang/bin/llvm-readelf HOSTCXX=/home/fabio/0day/clang/bin/clang++ HOSTAR=/home/fabio/0day/clang/bin/llvm-ar CROSS_COMPILE=powerpc-linux-gnu- --jobs=8 LLVM_IAS=1 ARCH=powerpc drivers/staging/rtl8723bs/

clang: error: unsupported argument '-me500' to option 'Wa,'
make[1]: *** [scripts/Makefile.build:272: scripts/mod/empty.o] Error 1
make[1]: *** Attesa per i processi non terminati....
make: *** [Makefile:1226: prepare0] Error 2

moreover I had to add LLVM_IAS=1, and ARCH=powerpc64 is not a valid architecture (used powerpc instead).

Could you help me?

thank you,

fabio
