Fix build-system: use xxx_LDADD instead of xxx_LDFLAGS

xxx_LDFLAGS place the libraries like '-lX11' or '-lXft' at the beginning of
the linker command. Some systems were not able to handle the situation and
this lead to a lot of unresolved symbols. Reading the documentation of
automake:

    ... you can use LDADD to do so. This variable is used to specify
    additional objects or libraries to link with; it is inappropriate for
    specifying specific linker flags, you should use AM_LDFLAGS for this
    purpose.

In addition we link against -lm in order to satisfy symbols refering to 'cos'
and 'sin'.
