I've applied it, with the following changes:

zlib being linked to, it should appear in inputs (used at runtime).
Since it's also listed as a Required package in the pkg-config file
(libfst.pc), it has to even be in propagated-inputs.

the lz4 license is bsd-2, not bsd-3

I've added bzip2 as an input.

The rest is just some cosmetic sugar.
