svn commit: r270882 - in head/lib/libc/arm: gen string sys

New Revision: 270882
URL: http://svnweb.freebsd.org/changeset/base/270882

Log:
  In ARM asm code, ensure that every ENTRY(foo) has a matching END(foo).
  The EABI unwind info requires a .fnend for every .fnstart, and newer
  binutils will complain about seeing two .fnstart in a row.  This change
  allows newer tools to compile our code.
