Thanks.  I've now applied the patch with the following ChangeLog entry.

        * sysdeps/unix/sysv/linux/arm/sys/ucontext.h: Don't include
        (gregset_t): Define without using elf_gregset_t.

        (R2): Rename to REG_R2.
        (R3): Rename to REG_R3.
        (R4): Rename to REG_R4.

        (struct _libc_fpstate): New.
        (fpregset_t): Define using struct _libc_fpstate.

This patch could go in because it was largely mechanical and copying code 
from elsewhere, but if you intend to make further contributions to glibc 
you should complete an FSF copyright assignment.
