This is the wrong fix. We are already passing CRYPTO= when no crypto
library is used. The only problem is that we are only passing it at
build time, while the .pc file is generated from .pc.in at install
time. So all we need to do is pass CRYPTO also at install time. My
proposal is therefore:

diff --git a/package/rtmpdump/rtmpdump.mk b/package/rtmpdump/rtmpdump.mk

I tested it, it works for me. If it does for you, can you submit it as
a proper patch?

Thanks!
