[rongqing.li at windriver.com]

From: Roy.Li <rongqing.li at windriver.com>

[YOCTO #2820]

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.

+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.
