[PATCH 0/6] Fix several cases of unstable test names

[Pedro Alves <palves at redhat dot com>]

I frequently diff testresults between builds in different build and
source directories, and that reveals several spurious differences.

Most are caused by the fact the some tests include the source or build
directories in their names, like:

  -PASS: gdb.arch/arc-tdesc-cpu.exp: set tdesc filename /home/pedro/gdb1/src/gdb/testsuite/gdb.arch/arc-tdesc-cpu.xml 
  +PASS: gdb.arch/arc-tdesc-cpu.exp: set tdesc filename /home/pedro/gdb2/src/gdb/testsuite/gdb.arch/arc-tdesc-cpu.xml
                                                                   ^^^^

  -PASS: gdb.base/startup-with-shell.exp: touch /home/pedro/gdb1/build/gdb/testsuite/outputs/gdb.base/startup-with-shell/unique-file.unique-extension 
  +PASS: gdb.base/startup-with-shell.exp: touch /home/pedro/gdb2/build/gdb/testsuite/outputs/gdb.base/startup-with-shell/unique-file.unique-extension 
                                                            ^^^^

  (I've underlined the differences above.)

though there are other causes too.  See each individual patch.

This series fixes all the spurious differences I see when native
testing on GNU/Linux.
