LADSPA: Fix undefined reference due to vectorization #4434

@PhysSong PhysSong commented Jun 17, 2018

Fixes #4030 by always linking math library.
Recent version of GCC optimizes some math function calls by vectorization. It requires a library mvec. GCC automatically links it if and only if math library is linked and target file needs the library.
Since LMMS doesn't use vector math function, LMMS won't be linked against mvec. It may cause crash on program loading and/or project loading.
Additionally, this pull request drop useless -Wl,-no-undefined for Windows(I guess it was needed by libtool) and a flag which isn't used elsewhere, (-Wl,)-Bsymbolic.
The MSVC check is for master, but I've added it here because it can be missed when syncing branches.
