ARM and AArch64 messages

More standarization of error/warning messages.  The ARM backend has
some multi-line error messages, which don't fit particularly well with
the GNU coding standard insistence that error messages shouldn't be
capitalized or have a full-stop.  I've replaced the line breaks with
semicolons.

So for instance the following
  system/path/to/ld: myobject.o: invalid special symbol `foo'.
  system/path/to/ld: It must be a global or weak function symbol.
becomes
  system/path/to/ld: myobject.o: invalid special symbol `foo'; it must be a global or weak function symbol
