Very little checking is performed on the validity of freelist metadata. Add a magic field to struct arena_header which can be used to detect memory corruption or whether a user tries to free something that isn't a malloc pointer. This feature can be enabled with -DDEBUG_MALLOC. Turn it on for development in mk/devel.mk. Cc: H. Peter Anvin <hpa@zytor.com> Signed-off-by: Matt Fleming <matt.fleming@intel.com>

Always strip the modules; they are too big unstripped. Specifically, we generate unstripped *.elf files, and then convert them to stripped *.c32 files. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
Before modules were dynamically loaded the boundary between GPL and non-GPL code was implicit because of the separate link domains for each module. With dynamic modules we need an explicit whitelist of core symbols that non-GPL code can link against at runtime without needing to be re-licensed under the GPL. Mark such symbols with __export, so that it is explicitly clear which symbols in the core can be linked against by non-GPL code. Reduce the visibility of symbols in both the core and ldlinux.c32 with -fvisibility=hidden. __export changes the visibility to 'default'. Signed-off-by: Matt Fleming <matt.fleming@intel.com>
Instead of hard-coding the python executable name use a make variable like we do for all other executables used during the build. This has the added bonus of allowing $(PYTHON) to be overridden on the command line, e.g. make PYTHON=python2 which is particularly useful for distributions where /usr/bin/python is actually python3.

Modules were linking against com32/gpllib/libcom32gpl.c32 even when NOGPL was set, so remove it from various modules Makefiles and use $(C_LIBS) in mk/elf.mk which already has the conditional-magic for $(GPLLIB). Also, the object files in com32/gpllib/ are not distributed in the release tarballs, which means that if a user does a 'make netinstall' they hit the following install error, install: cannot stat `com32/gpllib/*.c32': No such file or directory Add a $(INSTALLABLE_MODULES) variable to separate the list of build and install modules.

This extends commit 4678fd92a21e ("elflink: fix dependency problem in
cmenu/Makefile") and basically reverts commit fb543aa635ff ("com32:
Per-object file LDFLAGS"). By using the --as-needed ld argument we can
specify all the required shared libraries for a directory, even if not
all of the libraries are needed by every .c32 file. --as-needed takes
care of only creating DT_NEEDED entries for the shared libraries that
are actually required to resolve undefined symbols in a given module.
Furthermore, by using $(LIBS) we create a dependency between .c32
files and their shared libraries, which allows multiple make jobs to
run in parallel.

We really, really don't want to accidentally spew output to a debug port in production, so make it obligatory to define DEBUG_PORT or DEBUG_STDIO in order for the debugging code to be compiled in. Since DEBUG_STDIO just turns the debugging code into stdio references, we only need to compile the code for the DEBUG_PORT case. Add a commented-out line to mk/devel.mk to make it easier for users.
