Unfortunately this is a red herring and would have actually masked the
problem. The problem was that the imported vpxenc.c file uses the
maths symbols and as such we need to pull in -lm to the linking flags
used to link wcap. A patch should be on the list to fix this now.

(And the reason why some people didn't see this build error was that
they were getting -lm in their link flags from GLES/EGL via a Cairo
linked to those - probably via la files.)
