The Blackfin ISA does not have a "SHIFT" insn, it has either LSHIFT,
ASHIFT, or BXORSHIFT. So be specific when disassembling.
As fall out of this change, we need to update some assembler tests.

No need for these local structures related to formatting of output to
be writable, so constify the whole shebang.

There is a pseudo debug insn named ABORT that is commonly used in
simulation, so support it in the assembler too. The disassembler
already supports it.

* dwarf2read.c (die_needs_namespace) <DW_TAG_variable>: Add also
DW_TAG_constant.
gdb/testsuite/
* gdb.fortran/module.exp (fully qualified name of DW_TAG_constant):
New test.
* gdb.fortran/module.f90 (mod1) <var_const>: New constant.
We don't use the # character in the Blackfin assembly language, so let it
start end-of-line comments like most other assemblers.

The testcase was failing on various 64bit platforms, because the
debugging info said that the target type for a const type is a
4-byte reference. In the asm file, I used a .long directive, but
the size of .long is of course dependent on the platform. This
replaces this .long by a .4byte directive.
gdb/testsuite/ChangeLog:
* gdb.dwarf2/dw2-const.S: Use .4byte to reference the target
type of our const type.
This patch adds a new --enable-gdbserver=yes/no/auto command-line switch
in gdb/configure. The primary purpose is to allow a user to disable the
build & install of gdbserver when not desired. It also allows the user
to request gdbserver in which case the configure script will abort if
automatic building of gdbserver is not supported for that configuration.
The default keeps things as is: We automatically build gdbserver if
building for a native configuration and if gdbserver is supported for
that configuration.
gdb/ChangeLog:
* configure.ac: Add support for --enable-gdbserver.
* configure: Regenerate.
At AdaCore, this is mostly intended for ia64-linux, where we currently
do not want to distribute gdbserver. This will be useful in the context
of I417-033, where we are now using "make install" to determine what
needs to be packaged inside the GNAT Pro package.
