Revert for required ctl_speana_data function

Revert for required ctl_speana_data function

From gentoo timidity++-2.14.0 packages:

This will revert part of the commit from:

http://timidity.git.sourceforge.net/git/gitweb.cgi?p=timidity/timidity;a=commit;h=e73b53437dbc1e57e61dd4d0c1407784797b08d9

Because otherwise TiMidity++ simply won't build as per:

../interface/libinterface.a(xskin_c.o): In function `ctl_event':
xskin_c.c:(.text+0x17c): undefined reference to `ctl_speana_data'
collect2: error: ld returned 1 exit status
