This patch gets rid of a couple test fails in linespec.exp that we've 
observed from remote-host i686-mingw32 testing of Canadian cross 
toolchains for multiple targets.  As I observed in my notes on a 
previous patch

http://sourceware.org/ml/gdb-patches/2013-04/msg00053.html

in this configuration the test harness copies the source files to the 
working directory on the remote host and compiles them there, without a 
directory prefix.  So, tests that depend on a directory prefix being 
present (in this case, to disambiguate files that otherwise have the 
same name) can't be expected to work.

OK to commit?
