Fix a link error with libpcre

Libpcre was linked at the beginning of the link command. It was fine with
some compilers but not with others.

Libraries are supposed to be linked after every *.o file that use them or
some linker (gold?) reports errors about undefined references to functions.

Thanks to Micha Voss for reporting this problem and testing the solution.
