[gdb/testsuite] Fix gdb.arch/ppc64-symtab-cordic.exp without bzip2
After de-installing bzip2, I run into:
...
Running ppc64-symtab-cordic.exp ...
sh: bzip2: command not found
PATH: gdb.arch/ppc64-symtab-cordic.exp: failed bzip2 for \
src/gdb/testsuite/gdb.arch/cordic.ko.bz2
...
Fix these by:
- using remote_exec instead of catch system, and
- using file tail in the untested message.
I've tried making output redirection work with remote_exec, but that seems to
be broken, so we now:
- copy the file $f.bz2 into the desired location $dir/$f.bz2, and
- decompress the bz2 file using "bzip2 -df $dir/$f.bz2", resulting in a file
$dir/$f.
Factor out new function decompress_bz2 to make the test-case less verbose, and
also use it in gdb.arch/i386-biarch-core.exp.
Tested on x86_64-linux, without and with bzip2 installed.
