[v3,1/1] ljsyscall: new package

An FFI implementation of the Linux and NetBSD kernel ABIs for LuaJIT.

Signed-off-by: Danomi Manchego <danomimanchego123@gmail.com>

---

Note: this package requires LuaJIT specifically, so there is a depends-on
in the ljsyscall/Config.in, even though though it is included from a
menu with a "if BR2_PACKAGE_LUA || BR2_PACKAGE_LUAJIT" test around it.

v1 -> v2:
 - Removed unnecessary build time dependency on LuaJIT.
 - Specify -m 0644 during installation, since .lua files need not be executable.

v2 -> v3:
 - Config.in: add depends-on particular target architectures, like LuaJIT.  Note
           that this is not a compile time requirement but rather based on what
           the package itself supports.
 - Config.in: add comment stating when ljsyscall is hidden due to no LuaJIT
 - ljsyscall.mk: simplify ifeq / else ifeq block
 - ljsyscall.mk: use intermediate variable to simplify install lines

Danomi,

at this time, the version 0.9 was released (caution: with a new
subdirectory syscall/shared),
and a github helper was introduced in BR

  LJSYSCALL_SITE = $(call github,justincormack,ljsyscall,$(LJSYSCALL_VERSION))

(note: have you seen https://github.com/fperrad/ljlinenoise which uses it ?)

François.
