x86/build: Factor out fdimage/isoimage generation commands to standalone script
The build messages for fdimage/isoimage generation are pretty unstructured, just the raw shell command blocks are printed. Emit shortened messages similar to existing kbuild messages, and move the Makefile commands into a separate shell script - which is much easier to handle. This patch factors out the commands used for fdimage/isoimage generation from arch/x86/boot/Makefile to a new script arch/x86/boot/genimage.sh. Then it adds the new kbuild command 'genimage' which invokes the new script. All fdimages/isoimage files are now generated by a call to 'genimage' with different parameters. Now 'make isoimage' becomes: ...
