Hopefully this message will end into the email (formatted as per BR docs
21.5.5).

Following the helpful feedback from Thomas Petazzoni,
 I have improved upon my v2 patchset and included the changelogs
 below for reference.

I have checked the patch as following:

$ ./utils/check-package ./package/uftrace/*                         
85 lines processed
0 warnings generated

$ ./utils/test-pkg -d ../test-pkg -c ../uftrace.config -p uftrace -a
... (omitted for brevity)
45 builds, 36 skipped, 0 build failed, 0 legal-info failed

The package has also been tested with a virtualized ARMv7 rootfs.

Changes v2 -> v3:
	- added explainatation on why glibc is required
	- splitted long lines in Config.in
	- hashes are now calculated with sha256 instead of sha512
	- package now leverages generic-package instead of autotools
		- the prefix is now /usr instead of /usr/local to be more in line
			with other packages
		- definitions of the build commands are placed near the bottom of
			the makefile
		- added comments above the configuration options to explain why a
			check is needed

Changes v1 -> v2:
	- added myself to DEVELOPERS
	- removed configuration options that now are used in the makefile
	- removed dependency on UTIL_LINUX that was not needed
	- BR2_INSTALL_LIBSTDCPP is now "depends on" instead of "selects"
	- comment in Config.in is now at the end of the file
	- comment now will be shown only in the correct architecture
	- makefile has been sorted:
		- common configuration is at the top
		- architecture configuration is in the middle
		- feature flags are at the bottom

Changes v1:
	- initial proposal
