Extended Description

LLD doesn't currently support the -n, --nmagic option that is now required to compile the Linux Kernel VDSO shared object (shared object mapped into all user-space programs to provide support for system calls). The patch to enforce it:
https://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git/commit/?id=691efbedc60d2a7364a90e38882fc762f06f52c4

The -n option is similar to the -N, --omagic option that is partially supported by LLD (https://reviews.llvm.org/D26888). My understanding is:
-n (turn off page alignment)
-N (turn off page alignment, do not make text readonly)
LLD does not turn off page alignment with -N but it does apply the "do not make text readonly" part.

I suspect that supporting -n may be as simple as aliasing it to -zmax-page-size=1 but I'll need to double check for any other side-effects in ld.bfd first. Note that -zmax-page-size=1 doesn't quite do the same thing in ld.bfd as ld.lld, with ld.bfd the OutputSection alignment is set to whatever -zmax-page-size= is set to, even if there is an InputSection with a greater alignment, this can be overridden by the poorly documented ALIGN_WITH_INPUT optional section attribute. By contrast ld.lld always behaves as if ALIGN_WITH_INPUT is present.

The -n, --nmagic is also frequently used by embedded systems for micro-controllers and other systems that lack a memory management system and thus have no pages.
