Building u-boot tools with clang as a host compiler e.g. on FreeBSD with `gmake HOSTCC=clang CONFIG_USE_PRIVATE_LIBGCC=y tools` leads to many warnings [1] for every compiler invocation since commit 598e2d33. Part of mentioned commit imports linux patches:
- kbuild: LLVMLinux: Adapt warnings for compilation with clang
- kbuild: LLVMLinux: Add Kbuild support for building kernel with Clang
No version of clang supports the gcc fno-delete-null-pointer-checks though, but it is only passed to clang. Gcc does not have the clang specific Qunused-arguments for the target. Furthermore several warnings are disabled which aren't encountered in u-boot. Since such a build has worked for quite some time and works after removing these changes, just remove the clang specific handling to restore normal building with clang as hostcc.
[1] Actual warnings
GEN include/autoconf.mk.dep arm-freebsd-gcc: unrecognized option '-Qunused-arguments'
HOSTCC scripts/basic/fixdep clang: warning: argument unused during compilation: '-fno-delete-null-pointer-checks'

Applied to u-boot/master, thanks!
