ucl: fix shared build

libtool could not find -lwinmm and produced the following message:

*** Warning: linker path does not have real file for library -lwinmm.
*** I have the capability to make that library automatically link in when
*** you link to this library.  But I can only do this if you have a
*** shared version of the library, which you do not appear to have
*** because I did check the linker path looking for a file starting
*** with libwinmm and none of the candidates passed a file format test
*** using a file magic. Last file checked: /usr/lib/mxe/usr/lib/gcc/i686-w64-mingw32.shared/5.2.0/../../../../i686-w64-mingw32.shared/lib//libwinmm.a
*** The inter-library dependencies that have been dropped here will be
*** automatically added whenever a program is linked with this library
*** or is declared to -dlopen it.

*** Since this library must not contain undefined symbols,
*** because either the platform does not support them or
*** it was explicitly requested with -no-undefined,
*** libtool will only create a static version of it.

After that, it created a static library instead of shared one.
Even -no-undefined did not help.
