Comment 4 for bug 968561

Looks like Remi has been building php-5.4 for el6 the same way we have,
but on el5 the shared sqlite library is not included:

        --with-pdo-sqlite=shared,%{_prefix} \
  %if 0%{?fedora} >= 11 || 0%{?rhel} >= 6
        --with-sqlite3=shared,%{_prefix} \
  %else
        --without-sqlite3 \
  %endif

I'll see about getting the php54 package to handle el5 in a similar matter.
