package/alsa-lib/0005-remove-powerpc64-workaround.patch

   1 Linking currently fails on powerpc64 and powerpc64le when configured
   2 with --without-versioned, as follows:
   3 ../src/.libs/libasound.so: undefined reference to `.__snd_pcm_hw_params_set_format_first'
   4 (And many similar messages.)
   5
   6 This appears to be due to a very old (2003) workaround for powerpc64,
   7 (introduced by commit 06221f86) in include/alsa-symbols.h which alters
   8 symbol names. While it was probably necessary at the time, it does not
   9 appear to be necessary now and removing it fixes the build.
