unable to link lv2fil with libm.so, crashes in Ardour

[https://www.google.com/accounts/o8/id?id=aitoawlxwqh0ga5xfp1zvtbyyifjetjvbae5cki]

When I try to run the plugin from Ardour 2.8.7 r6628, I get the following error:

Unable to open library /usr/lib/lv2/filter.lv2/filter.so (/usr/lib/lv2/filter.lv2/filter.so: undefined symbol: floor

I have tried to link the math library by adding

conf.env.append_value('CCFLAGS', '-Wall -lm')

to the 'def configure(conf)' target, but the result is no different. Do I need some special flags to compile Ardour? I can't imagine it doesn't load the math library already. The other LV2 plugins I compiled (Calf, SWH, Invada) work fine.
