Use a small local file instead of fetching one from Stackage

[chreekat]

This would be a fix for #10950, except that the test is failing and I don't know why. Pointers welcome.

[chreekat]

When I ran the test locally, I get an error that looks like the original fix hadn't been applied. It looks for a file with a space in its name and can't find it.

The test does pass if I go back to the previous commit.

I can't see why my change would have broken cabal again...

Maybe I'm using the wrong cabal lib. That was also fun to figure out:

I try --intree-cabal-lib, and it says, Missing: --test-tmp ARG. Fair.

I try --intree-cabal-lib --test-tmp /tmp, and it says, Missing: --test-tmp ARG. Ummm

I try --intree-cabal-lib . --test-tmp /tmp, and it says, Warning: Specifying an absolute path to the project file is deprecated. And fails with The Package location './Cabal' does not exist.. Where is the absolute path? Huh?

I try --intree-cabal-lib $PWD --test-tmp /tmp, and it finally starts building. But now I am specifying an absolute path...?

Unfortunately, the test still failed.

/tmp/cabal-testsuite-1160356/cabal.config : withBinaryFile: does not exist (No such file or directory)

To me this looks like it has not removed the trailing space from the filename cabal.config .

[chreekat]

Yeah, as it's being discussed at #10954 , this is currently by design, which comes as a shock to me.
