fix the pcre existence checking

when check if there is pcre, the configure file always check
the host dir. now we make it work by adding correct prefix for
cross-compile environment.

When enable pcre-module, we see a QA warning because rpaths
hardcoded into the build, rpaths are not needed, so lets turn
this off.
