Profile-directed feedback and remote testing

[Mark Mitchell]

When we generate data for feedback, we insert the .gcda name into the 
object file as an absolute path.  As a result, when we try to do remote 
testing, we lose, as, in general the remote file system does not have 
the same file hierarchy as the build system.

I understand why we generate an asbolute path; we want to make sure that 
the data ends up there, not in the directory where the user happens to 
run the program.  So, I intend to disable these tests when $host != 
$target.  Any objections, or better ideas?
