This new variable is extremely useful when iterating on creating a large package,
as otherwise you have to wipe the source and rebuild each time you make a mistake
with the patches or build.sh script.
Simply set TERMUX_PKG_QUICK_REBUILD=true in build.sh if a build fails and then the
TERMUX_PKG_SRCDIR and TERMUX_PKG_BUILDDIR will not be touched when you rebuild,
including that the patches will not be applied again. When you're done iterating,
diff for any new patches, save them, and remove this variable before rebuilding
from scratch, hopefully for the last time. ;)
An example is shown for the giant libllvm package, where other modifications are
also excluded if this variable is set.
Unlike the NDK clang, the on-device clang has already been patched to add an rpath
to the Termux-prefixed library path, so only have the build script add the rpath
flag for NDK builds.
termux_step_install_service_scripts is run after
termux_step_post_make_install and loops over the new array
TERMUX_PKG_SERVICE_SCRIPT to add service scripts for termux-services.
The service scripts are usually only a one-liner so we might just as
well define it in a variable like TERMUX_PKG_SERVICE_SCRIPT.
TERMUX_PKG_SERVICE_SCRIPT should be an array on the format
("daemon-name" 'script to execute' "another daemon" 'multi\n line\n script'),
i.e. it should be of even length with name + script where the script
part preferably is within single quotes (to avoid accidental expansion
of for example $HOME).
By defining __TERMUX__ and __TERMUX_PREFIX__ in <sys/cdefs.h> (which is
basically always included) one can more easily target Termux
specifically, both when cross-compiling packages and when code is built
on-device.
