[pulseaudio-discuss] [PATCH] configure.ac: look for function `backtrace` also in library `ubacktrace`

Using OpenEmbedded with `minimal-uclibc` for `MACHINE = "beagleboard"` compilation fails with the following error [1].

        […]
          CCLD   pulseaudio
        ./.libs/libpulsecommon-0.9.22.so: undefined reference to `backtrace_symbols'
        ./.libs/libpulsecommon-0.9.22.so: undefined reference to `backtrace'
        collect2: ld returned 1 exit status
        make[3]: *** [pulseaudio] Error 1

Using uClibc `backtrace` is in the library `ubacktrace` and needs to be searched in there. This patch is used successfully in OpenEmbedded [2].

1. Please also apply this patch to the stable(?) branch.
2. I hope the commit message uses the correct terminology.
