For x86, the default kernel image is compressed, but other architectures
allowed both compressed and uncompressed kernel images to be built.  Add
a test to detect which one this is, and either name the output file
"vmlinuz" for a compressed image, or "vmlinux" for an uncompressed
image.

For x86 this change is a no-op, but other architectures depend on this.

After applying this series, I think the excessive
"Installing ..." messages are a bit annoying.


masahiro@grover:~/workspace/linux-kbuild$ make INSTALL_PATH=~/foo install
sh ./scripts/install.sh 5.12.0-rc3+ arch/x86/boot/bzImage \
System.map "/home/masahiro/foo"
Installing compressed kernel
installing 'arch/x86/boot/bzImage' to '/home/masahiro/foo/vmlinuz'
installing 'System.map' to '/home/masahiro/foo/System.map'
Cannot find LILO, ensure your bootloader knows of the new kernel image.



Since 03/20 added a new log in the 'install' function,
can we drop this "Installing compressed kernel" message?

Same here.

This message tends to be wrong.
For example, arch/arm/boot/uImage is gzip-compressed,
but it says "Installing normal kernel".
