The layout of the pacakge direcotry has changed, as upstream has added
more than just trace-cmd in the repository (e.g. kernel-shark).
However, the buildsystem for trace-cmd is... unconventional:
- the top-level Makefile will recurse into the trace-cmd/
sub-directory, but does not pass any variable on the $(MAKE) command
line; instead, it exports them in the environment, e.g.:
export CFLAGS
- the top-level Makefile appends some definitions to CFLAGS et al.,
sometimes with a simple append-assignment, sometimes with an
overriden append-assignment, e.g.:
CFLAGS += -DVSOCK
override CFLAGS += -DNO_PTRACE
- the top-level Makefile does not export all the variables. For
example, LDFLAGS is not exported;
- the Makefile in the trace-cmd/ sub-directory expects some variables
to be set, which is done by the top-level Makefile.
As a consequence, we can no longer pass our variable definitions as make
variable defintions on the command line; we must pass them in the
environment. Note that for some, like CFLAGS, that would still work, but
it would not for others, like LDFLAGS; for consistency, we put all in
the environment.
We can however use the provided 'make install', that behaves as
expected. But we must repeat most environment variables; especially, we
duplicate TARGET_CONFIGURE_OPTS as it has PATH et al. which are needed
by the top-level Makefile to properly detect tools (e.g. swig), which it
uses to decide what it should install.
Drop upstreamed patch.
Update the licensing information: new license files have been added in a
sub-directory, and the top-level COPYING now only references those two
(rather than being the actual text of the GPL-2).
Use two spaces in hash file.

[yann.morin.1998@free.fr:
- keep using a git clone
- unbreak the build:
- use the default make target rule, or the plugins and python
bindings be built at install time, with the host compiler
- use the default install target rule
- expand commit log:
- detail buildsystem issues
- add new license files and their hashes
