So the build script tries to find clang1 file instead of clang.
GEN Makefile
HOSTCC scripts/basic/fixdep
/bin/sh: line 1: clang1: command not found
make[2]: *** [/build/linux/scripts/Makefile.host:95: scripts/basic/fixdep] Error 127
make[1]: *** [/build/linux/Makefile:564: scripts_basic] Error 2
make: *** [Makefile:219: __sub-make] Error 2
