support for profiling

[amigalemming]

When I compile a program with profiling I get linker errors like these:

/cabal/lib/x86_64-linux-ghc-7.8.3/cufft-0.1.0.3/libHScufft-0.1.0.3_p.a(Plan.p_o):(.text+0x5d98): undefined reference to `cufftPlan3d'

...

When I change build-type from Configure to Simple in cufft.cabal and add pkgconfig-depends: cufft-6.0 then I can successfully compile with profiling.

I wasn't able to reproduce this problem myself, but I suspect it has to do with autoconf not being run properly. I've just pushed a commit which changes the build-type to Custom and works the same was as the cuda package. Hopefully, this should fix the problem. Let me know if it works or not.

We have avoided using pkgconfig because it doesn't always find where cuda was installed.
