Add substitutions to `lapack.pc.in`, in order to ensure that the generated `lapack64.pc` file correctly references the index64 library and BLAS dependency. It seems that other pkg-config templates have been updated as part of Reference-LAPACK#462 but this one was omitted. As a result, finding a lapack64 via pkg-config gave a non-index64 libraries.

Very initial proof of concept PR, related to #461
This adds a BUILD_INDEX64 option which manages names for libraries.
Should have no effect with the default set to OFF.
When switched on, it will build the 64-suffixed libs.
Not a lot of testing done yet.Just checked that BLAS64, CBLAS64, LAPACK64 and LAPACKE64 are building, with correct cmake and pkg-config files.1/11/2020:
BLAS and CBLAS tests are working fine, LAPACK tests are still failing.All tests are passing!
TODO:
Handle header file naming.
Fix printf/fprintf so that they don't give warnings of incompatible types.
