PATCH: call aclocal for PCRE in buildconf

[Brian Pane]

I found that the configure.in in recent releases of PCRE uses some 
autoconf macros that won't work unless aclocal is called first to 
produce a proper aclocal.m4: AC_PROG_LIBTOOL and AC_LIBTOOL_WIN32_DLL

This buildconf patch fixes it for me (and works with both the new PCRE 
5.0 and the old version that's currently in the httpd-2.1 tree).

Before I commit it, though, does anyone know of a system where it's not 
safe to assume aclocal exists?

Thanks,
Brian
