new 57e761f72 build: Omit default priority ELF symbol.
57e761f72 is described below
commit 57e761f7242254e0a15d498972d87704c709b07e
Author: Marco Casaroli <[email protected]>
AuthorDate: Sun Jul 26 17:00:11 2026 +0200
build: Omit default priority ELF symbol.
Do not define nx_priority for applications that use SCHED_PRIORITY_DEFAULT.
The ELF loader already uses its scheduler default when the symbol is absent,
avoiding the invalid priority-zero value previously encoded by Application.mk.
Keep emitting nx_priority, and retaining it through stripping, for explicit
numeric priorities.
