Works just fine for me.

$ make libsqlite3.la
[...]
$ grep dlname .libs/libsqlite3.lai
dlname='../bin/cygsqlite3-0.dll'
$ grep dlname .libs/libsqlite3.la
dlname='cygsqlite3-0.dll'
$ grep dlname libsqlite3.la
dlname='cygsqlite3-0.dll'
$ ./libtool --mode=install install libsqlite3.la /usr/local/lib
[...]
$ grep dlname /usr/local/lib/libsqlite3.la
dlname='../bin/cygsqlite3-0.dll'
$ ls /usr/local/bin/*sqlite3*
/usr/local/bin/cygsqlite3-0.dll
$ ls /usr/local/lib/*sqlite3*
/usr/local/lib/libsqlite3.a      /usr/local/lib/libsqlite3.la
/usr/local/lib/libsqlite3.dll.a
