[PATCH] build: avoid compilation failure when building without PCRE support

[Jim Meyering]

Independent of today's patch series, here's a fix for a build
failure reported by Eric Blake:

      CC       pcresearch.o
    pcresearch.c:112:1: error: expected '=', ',', ';', 'asm' or '__attribute__' 
before 'Pexecute'
    make[2]: *** [pcresearch.o] Error 1

That happens only when configure-time tests fail to find PCRE support.

Here's the fix:
