[LTP] [PATCH v3 0/4] Automatically generate syscalls.h

[Andrea Cervesato]

The problem we have at the moment is that all syscalls input files must
be changed by hand each time we need to test a new syscall. The idea is
to simplify this process, providing a script that is able to read from
kernel sources and to generate all syscalls files we need.

This patch set adds a new command inside the syscalls folder and
it refactors the previous regen.sh code.
The new way we have to generate the syscalls.h file is the following:

	include/lapi/syscalls/generate_arch.sh 		path/to/kernel/source
	include/lapi/syscalls/generate_syscalls.sh 	path/to/syscalls.h

Scripts are independent and they can be run separately.
generate_syscalls.sh is the equivalent of regen.sh, but its code has
been cleaned up.
