patch to fix detection of libpng and libpcre on 64-bit platform

Description of problem:
64-bit lib64slang2 package doesn't contain png and pcre slang modules while 32-bit counterpart contains them.

The cause of this is that configure script only searches <>/lib directory for libraries and can not find them in <>/lib64 directory.

Version-Release number of selected component (if applicable):
all versions of slang beginning with at least Mageia 2 and up to the current one in cauldron.

I do not know if these modulea are used by anyone but this is inconsistency between 32 and 64-bit versions of the same package and I think it should be fixed.

I do attach a simple patch for the spec file that fixes detection of both libpng and libpcre and also makes detection of zlib more consistent with 64 architecture (configure scripts finds 32-bit version of zlib instead of 64-bit one without this addition).
