Missing symbol from the shared library

[dbermond]

The symbol WebRtcIlbcfix_InitDecode is missed from the shared library. The following command produces no output:

$ nm -D libilbc.so | grep 'WebRtcIlbcfix_InitDecode'

As a result, applications that uses this function and tries to link against libilbc.so fails to build. For example, FFmpeg is showing me this error:

/usr/bin/ld: /tmp/ffconf.mxjpOf0E/test.o: in function `check_WebRtcIlbcfix_InitDecode':
test.c:(.text+0x3): undefined reference to `WebRtcIlbcfix_InitDecode'
collect2: error: ld returned 1 exit status
ERROR: libilbc not found

This can be fixed by the following modification, but I'm not sure if it would be desirable for the project. Probably there could be a better solution.

Darn, I fixed this for init_encode but not init_decode…

Thank you for fixing this! Working fine now :)
