Description: enable cross building

ffindex fails to cross build from source, because it uses mpicc. mpicc

is unfixable in terms of cross building, which is why it is being moved

to pkg-config upstream. Rather than wrap your build in mpicc, you can

compute the relevant flags using pkg-config just like any other library.
