[PUSHED] gdb/testsuite: compile gdb.linespec/cp-completion-aliases.exp as C++

[Andrew Burgess]

Noticed in passing that the prepare_for_testing call in
gdb.linespec/cp-completion-aliases.exp does not pass the 'c++' flag,
despite this being a C++ test.

I guess, as the source file has the '.cc' extension, all the compilers
are doing the right thing anyway -- the source file uses templates, so
is definitely being compiled as C++.

I noticed this when I tried to set CXX_FOR_TARGET (but not
CC_FOR_TARGET) and spotted that this script was still using the C
compiler.

Fixed in this commit by adding the 'c++' flag for prepare_for_testing.

Hi,

this is an instance of 
https://sourceware.org/bugzilla/show_bug.cgi?id=30380 .

I already had this fixed in a branch, but hadn't had time to submit.

FWIW, it's the top commit of 
https://github.com/vries/gdb/commits/testsuite/old-gcc .

Thanks,
- Tom

Sorry for duplicating this work.  I ran into this case while working on
some other patch and I didn't want to have to carry around such a
trivial local patch.

Hope this didn't cause you any serious problems.

Thanks,
Andrew
