libvbucket RPM is missing /usr/lib64/libvbucket.la file

The libvbucket1 rpm does not include the libvbucket.la file. The libcouchbase.la file references libvbucket.la as a dependency.

Linking via libtool against libcouchbase fails because of this. For example, compiling the php-ext-couchbase package fails like:

/bin/sh /root/code/php-ext-couchbase/libtool --mode=link cc -DPHP_ATOM_INC -I/root/code/php-ext-couchbase/include -I/root/code/php-ext-couchbase/main -I/root/code/php-ext-couchbase -I/usr/include/php -I/usr/include/php/main -I/usr/include/php/TSRM -I/usr/include/php/Zend -I/usr/include/php/ext -I/usr/include/php/ext/date/lib -I/usr/include/ -DHAVE_CONFIG_H -g -O2 -o couchbase.la -export-dynamic -avoid-version -prefer-pic -module -rpath /root/code/php-ext-couchbase/modules compress.lo couchbase.lo fastlz/fastlz.lo -lz -lcouchbase
grep: /usr/lib64/libvbucket.la: No such file or directory
/bin/sed: can't read /usr/lib64/libvbucket.la: No such file or directory
libtool: link: `/usr/lib64/libvbucket.la' is not a valid libtool archive
make: *** [couchbase.la] Error 1

I created a fake libvbucket.la by copying /usr/lib64/libcouchbase.la and editing it, and it allowed the compile to succeed.
