new 067b0ccf2 Application.mk:define application attribute in elf symbol
067b0ccf2 is described below
commit 067b0ccf2875357f0f6a6c4ffea503a468d9689b

Application.mk:define application attribute in elf symbol
Emit --defsym for nx_stacksize, nx_priority (and nx_uid/nx_gid/nx_mode
under CONFIG_SCHED_USER_IDENTITY) into MODLDFLAGS so the ELF binary
loader can recover the application's configured attributes at load time.
Also skip builtin registration for separately-built module ELFs
(BUILD_MODULE instead of DYNLIB).
