New test introduced in r257120 was failing on linux. The reason for that the regex for setting the breakpoint was being applied to the "default file", which in this case was the asm file containing the definition of the sleep() syscall (because after attach, we are stopped in the sleep function). I have changed this use the more customary way of setting the breakpoint and specifying the source file name explicitly. llvm-svn: 257160
