h8300: use cc-cross-prefix instead of hardcoding h8300-unknown-linux-
It believe it is a bad idea to hardcode a specific compiler prefix that may or may not be installed on a user's system. It is annoying when testing features that should not require compilers at all. For example, mrproper, headers_install, etc. should work without any compiler. They look like follows on my machine. $ make ARCH=h8300 mrproper ./scripts/gcc-version.sh: line 26: h8300-unknown-linux-gcc: command not found ./scripts/gcc-version.sh: line 27: h8300-unknown-linux-gcc: command not found make: h8300-unknown-linux-gcc: Command not found make: h8300-unknown-linux-gcc: Command not found [ a bunch of the same error messages continue ] $ make ARCH=h8300 headers_install ./scripts/gcc-version.sh: line 26: h8300-unknown-linux-gcc: command not found ./scripts/gcc-version.sh: line 27: h8300-unknown-linux-gcc: command not found make: h8300-unknown-linux-gcc: Command not found HOSTCC scripts/basic/fixdep make: h8300-unknown-linux-gcc: Command not found WRAP arch/h8300/include/generated/uapi/asm/kvm_para.h [ snip ] The solution is to delete this line, or to use cc-cross-prefix like some architectures do. I chose the latter as a moderate fixup. I added an alternative 'h8300-linux-' because it is available at: https://mirrors.edge.kernel.org/pub/tools/crosstool/files/bin/x86_64/8.1.0/ Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
