To speedup the depends cached builds, remove some some clutter from the package
files. This mainly incldues removing all the shared libraries and .la
linker files. It also gives stronger guarantees that monero only links
the static libs without any external rvalues.
Clang needs to get its cctools path passed directly for the hid build to
succeed.
Make gperf a permanent external dependency.
Remove pcsc from depends.
