* hyperscan: 5.1.0 -> 5.1.1
* provide misc utils needed by build
* hyperscan: build shared libs only by default
Only consumer now (rspamd) needs only the shared libs
+ add a switch to build both shared and static if needed
+ cleaner outputs (previously there was static lib and symlink to shared lib in $dev)
+ fix pkgconfig template for v5.1.1 otherwise "includedir" path is wrong
* hyperscan: restrict to x86_64-linux
Fails to find 'nm' on x64 darwin
