Author: emaste Date: Tue Jun 12 13:32:42 2018 New Revision: 334998 URL: https://svnweb.freebsd.org/changeset/base/334998 Log: linux64: use linux output target for linux_vdso.so linux_vdso.so provides the vdso for the linuxulator's amd64 target and is mapped into a Linux binary's address space. Thus it should be a Linux-style .so, which has the ELF OS/ABI unset. It turns out that ELF Tool Chain elfcopy/objcopy also has a bug where the OS/ABI field is unset, regardless of the specified --output-target, so this change is a no-op with the default in-tree toolchain. This is a real fix when using external binutils, and the ELF Tool Chain bug will be fixed in the future.
