Some embedded targets don't have full support for argc/argv. argv
may print as "0x0" or as an address with a symbol name following.
This causes problems for the regexps in the style.exp line-wrapping
tests that assume it always prints as an ordinary address in backtrace
output.
This patch generalizes the regexps to handle these additional forms
and reworks some of the line-wrapping tests to account for the argv
address string being shorter or longer than a regular address.

This patch fixes some testcases that formerly had patterns with
hardwired "/" pathname separators in them, which broke when testing on
(remote) Windows host.

These testcases assume host==build or that the remote host has a Posix
shell to run commands in. Don't try to run them if that's not the case.

When a GDB stub is run via "target remote |", it sometimes produces
extra output that ends up mixed with GDB's own output. For example,
QEMU's built-in GDB stub responds to the vKill packet by printing
nios2-elf-qemu-system: QEMU: Terminated via GDBstub
before exiting.
This patch fixes the regexp in gdb.base/hook-stop.exp to allow such
messages between GDB's "continuing" and "Inferior killed" messages.

Sorry, I don't remember the state of this or why I didn't approve it.
Anyway I looked through this and I think it is fine.
