Err... I see. The configure warns when we specify --host for native
build. We need to handle native build case.
It's not true that it will automatically detect cross compilation.
When we don't specify --host for cross compilation (just specify CC
variable), it compilains:
checking whether the C compiler works... configure: error: cannot run C
compiled programs.
If you meant to cross compile, use `--host'.
Well, specifying --host itself is right way. But yes, there are many
misunderstandings in the past between --host and --build. Configure
warns when --host is specified on native build.
I think that we can ignore this warning. Specifying --build along with
--host can kill this warning.
Following change works both of native and cross build.
Note:
There are three things: host, build, and target.
HOST: The machine where the executable will run.
BUILD: The machine where the executable is about to be built.
TARGET: The machine where the executable will target.
(Only valid for development tool, such as compiler,
assembler, linker.)
