Add per-firmware object directory supportfor-hpa/elflink/per-fw-obj
Now that we have multiple firmware backends it no longer makes sense to write object files to the same directory as their source. A better solution is to write the object files to a per-firmware directory under a top-level object directory. The top-level object directory can be specified on the command-line with the O= variable, e.g. make O=/tmp/obj. If no top-level object directory is specified an 'obj' directory is created in the top-level of the Syslinux source repository. All the existing make targets continue to work as before, however now they apply to all firmware backends, e.g. 'make installer' will build the BIOS, 32-bit EFI and 64-bit EFI installers and place them under $(OBJ)/bios, $(OBJ)/efi32 and $(OBJ)/efi64 respectively. Note unlike every other bit of Syslinux, the gpxe objects are still kept in the src directory, e.g. gpxe/src, since gpxe is only required by the BIOS backend. It is possible to specify a make target for a specific firmware or list of firmware with the following syntax, make [firmware[,firmware]] [target[,target]] To clean the object directory for just the BIOS firmware type, 'make bios clean' To build both the 32-bit and 64-bit EFI installers type, 'make efi32 efi64 installer' Since the Syslinux make infrastructure is now more complex a new file doc/building.txt has been created to explain how to build Syslinux. The top-level Makefile now exports some make variables for use in module Makefiles, - topdir - the top-level source directory of the Syslinux repository, e.g. /usr/src/syslinux - objdir - the top-level object directory for the firmware backend currently being built, e.g. /obj/syslinux/bios - SRC - the source directory in the Syslinux repository for the module currently being built, e.g. /usr/src/syslinux/com32/libupload - OBJ - the object directory for the module currently being built, e.g. /obj/syslinux/bios/com32/libupload Since we're rewriting the Makefile infrastructure anyway it seemed like a good idea to add parallel support. By writing subdirectories as prequisites for make targets the objects in those subdirectories can be built in parallel. Signed-off-by: Matt Fleming <matt.fleming@intel.com>

+ Building Syslinux
+
+From Syslinux 6.0 onwards there is support for three different
+firmware backends, BIOS, 32-bit EFI and 64-bit EFI. To allow users the
+flexibility to build only the firmware they need the Syslinux make
+infrastructure has become more complex.
+
+The Syslinux make infrastructure understands the following syntax,
+
+ make [firmware[,firwmware]] [target[,target]]
+
+If no firmware is specified then any targets will be applied to all
+three firmware backends. If no target is specified then the 'all'
+target is implicitly built.
+
+For example, to build the installers for BIOS, 32-bit EFI and 64-bit
+EFI type,
+
+ make installer
+
+TO build the BIOS and 64-bit EFI installers type,
+
+ make bios efi64 installer
+
+To delete all object files and build the installer for 32-bit EFI
+type,
+
+ make efi32 spotless installer
+
+
+ ++++ THE OBJECT DIRECTORY ++++
+
+A custom top-level object directory can be specified on the make
+command-line by using the O= variable, e.g.
+
+ make O=/tmp/syslinux-obj efi32
+
+will build the 32-bit object files under /tmp/syslinux-obj/efi32. If
+no object directory is specified then object files will be written to
+an 'obj' directory in the top-level of the Syslinux source.
