[ninja] Don't remove response files for verbose builds

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Csaba Osztrogonác]

In bug137606 I suggested to disable using response files if we use 
VERBOSE build to be able copy/paste the command and be able run manually.
Unfortunately the linking fails in this case with "Argument list too long".

The another problem is that ninja automatically removes response files. But we 
can use "-d keeprsp" not to remove rsp files if we have ninja 1.5.1 or newer.

Response file are necessary because CMake + Ninja does not know how to add files to ar archives in chunks. Instead it will try to add them using one command invocation.

"-d keeprsp" is available since ninja version 1.4.0, so created the feature according to this.

The idea is good, but I suggest some minor style changes.

I think chomp is better choice here:
chomp(my $ninjaVersion = `ninja --version`);

We can do it in one line:
push @args, "-d keeprsp" if (version->parse(determineNinjaVersion()) >= version->parse("1.4.0"));
