Include file pcre.h missing in binary dist, meaing I_S plugins can't be built

The binary distributions of MariaDB now contains the includefiles and libraries needed to build most plugins. In the case of INFORMATION_SCHEMA plugins though, the (generated by a build) pcre.h file is missing, this is include by item.h which in turn in included by sql_lex.h and so on. For example it seems not to be possible to build the qc_info plugin without pcre.h. This seems to be the only missing component for this to work.
