[kaffe] config.frag files for NetBSD

[Kiyo Inaba]

Hi,

Thanks for the official support of crosstools in the latest NetBSD,
I tried to compile all Kaffe configurations available for NetBSD
(alpha, arm, m68k, mips, powerpc, sparc).

Attached patch deleted unneeded defs in config.frag files for these
configurations. I think similar mods can be applied to all other
platforms.

The mods can be devided into four types
1. Delete 'Khost_cpu' and 'Khost_os' defined in some files.
2. 'ac_cv_sizeof_int' etc. are now properly handled by 'configure'
   even for cross compiling.
3. 'ac_cv_c_char_unsigned' is now set to 'no', when cross compiling.
4. 'CFLAGS' is now used only to append mandatory settings for the port.

Typical way of cross compiling is done by
    ../kaffe-1.1.0/configure --host=m68k--netbsdelf --enable-debug \\
    --with-staticbin --with-staticlib --with-staticvm \\
    --with-threads=unix-jthreads --without-x --without-sound \\
    --with-engine=intrp \\
    --with-rt-jar=$PWD/../kaffe-1.1.0/libraries/javalib/rt-precompiled.jar

At least for alpha, arm, m68k, powerpc, sparc, this new config.frag
works fine to make 'kaffe-bin', and with slight modification, mips is
also ok but it's another topic.

Is this mod applicable?

Kiyo
