* configure.ac: Add -fvisibility=hidden to GPGME_QT_CFLAGS if gcc supports the flag. -- With this change all defined symbols are hidden by default, so that they are not exported anymore. All symbols that are part of the ABI and that shall still be exported are already marked as having default visibility. GnuPG-bug-id: 5906

dnl Under Linux, make sure that the old dtags are used if LD_LIBRARY_PATH

dnl is defined. The issue is that with the new dtags, LD_LIBRARY_PATH has

dnl the precedence over the run path, so that if a compatible MPFR library

dnl is installed in some directory from $LD_LIBRARY_PATH, then the tested
