Marc Hartmayer ed4c68e867 common.mak: improve cross compilation support ...

Introduce `BUILD_ARCH` and `(CC|LINK|...|OBJDUMP)_FOR_BUILD` variables
in order to properly support the build of tools that generate code or
data during the build process. Replace existing variables `HOSTCC` with
`CC_FOR_BUILD` and `HOSTCFLAGS` `CFLAGS_FOR_BUILD`. The Makefile
variables for the `HOST_ARCH` are unchanged.
