This change adds support for the -mcall-ms2sysv-xlogues option on NetBSD/x86 systems, resolving undefined references in tests related to the Microsoft (MS) ABI calling convention. The fix aligns with a previous change for FreeBSD/x86, but omits the emission of .note.GNU-stack sections as they are unnecessary on NetBSD. The changes were verified without regressions on NetBSD and Linux x86_64.
