Maciej W. Rozycki 93a24ba79b PR gas/20312: Do not pad sections to alignment on failed assembly
Correct a regression from commit 85024cd8bc ("Run write_object_file
after errors") causing unsuccessful assembly, which may be due to any
reason, such as supplying a valid source like this:

	.text
	.byte	0
	.err

to terminate with an assertion failure like:

test.s: Assembler messages:
test.s:3: Error: .err encountered
../as-new: BFD (GNU Binutils) 2.24.51.20140628 internal error, aborting at .../gas/write.c line 608 in size_seg
../as-new: Please report this bug.

on targets whose default text section alignment is above 0, typically
RISC machines.

This is due to an attempt to set last text section's frag alignment to
0, requested from `subsegs_finish_section' where `frag_align_code
(alignment, 0)' is called with `alignment' set to 0 rather than the
section alignment if `had_errors' has returned true.  The call to
`subsegs_finish_section' is made from `subsegs_finish' from
`write_object_file' at unsuccessful completion, which previously wasn't
made.

Always set last section's frag alignment from the section alignment
then, forcing no section padding instead if completing unsuccessfully,
so that in that case alignment padding is still suppressed from any
listing generated, fixing assertion failures for these targets:

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
